Guest Post by Milan Adams
On a January morning off the island of El Hierro, a wooden boat comes in under tow. It sits low and packed, passengers pressed shoulder to shoulder, almost all of them men in their twenties and thirties. Spain’s maritime rescue service brings the hull alongside a patrol vessel; one man is carried ashore on a stretcher and does not move. Nobody speaks in the filmed sequence. The only sounds are water against fibreglass and an engine throttling down.
That boat is the visible end of a route beginning some 800 kilometres south, on a peninsula of the Mauritanian coast, and it is the opening image of a 47-minute documentary called Replacing Europe, made by an investigative outfit named Muckraker. The film walks the whole of it over two months — Nouadhibou, the Canary Islands, mainland Spain, France, the Channel — and captures the machinery rather than the drama. Smugglers run the crossings. Publicly financed charities run reception and onward transport. Volunteers handle the last few kilometres. Governments underwrite nearly all of it. A man on the payroll of a United Nations agency, identified in the film as Sheikh M. Kromah, says on camera that Spain has a financial motive to keep the boats arriving.
Watching it, a viewer could reasonably conclude that Europe is being overrun by pirogues. The numbers say something more complicated. Spain took 63,970 irregular arrivals in 2024 and added 474,454 residents in the same year. The Union’s foreign-born population grew by 1.9 million in 2025 against 239,000 irregular crossings in 2024. The boats are the loud part. Most European immigration arrives by air, on visas, through family reunion and labour schemes, and generates almost no television footage at all.
So why has a semi-formal pipeline across the Sahara and the Atlantic become the visible edge of Europe’s demographic policy? The answer is sixty years long, and almost nobody chose it.
Milton Friedman, who spent a career arguing that institutions shape behaviour more reliably than intentions do, gave the resulting constraint its most quoted form. “You cannot simultaneously have free immigration and a welfare state.” — Milton Friedman
Read as an argument against immigration, the line is too tidy. Read as an observation about design, it holds up rather well. Europe built contributory welfare systems for a growing population and then attached them to an immigration regime designed for entirely different purposes, and the two have been renegotiating the terms ever since.
The story starts with a labour shortage and a confidence that turned out to be misplaced.
Postwar reconstruction ran on manpower. West Germany’s economy expanded faster than its workforce, and from 1955 onwards Bonn signed a series of bilateral agreements to import labour: Italy first, then Greece and Spain in 1960, Turkey in 1961, Morocco in 1963, Portugal in 1964, Tunisia in 1965, Yugoslavia in 1968. France ran its own recruitment through the Office National d’Immigration. The Netherlands brought in Moroccans and Turks. Belgium signed agreements in 1964. Sweden recruited Finns, Greeks and Yugoslavs.
The operative word in German policy was Rotation. Workers would come, earn, and rotate home, replaced by fresh recruits from the same villages. By 1973 the Federal Republic hosted roughly four million foreigners, of whom some 2.6 million were in work. Then the first oil shock hit, unemployment rose, and on 23 November 1973 Bonn stopped recruiting. France followed the following year.
Rotation ended that day, and almost nobody noticed for a decade. Workers already inside Germany faced a choice between leaving permanently and bringing their families, and they overwhelmingly chose the second. Spouses arrived under family reunion provisions, children followed, and by the early 1980s it was clear that the guest workers had become settlers. The same pattern repeated in France, the Low Countries and Scandinavia, with variations but no exceptions.
What matters for the present is the assumption buried underneath. Every European welfare state built in the twentieth century — Bismarck’s pension insurance of 1889, Beveridge’s postwar settlement in Britain, the continental systems that followed — assumed a population that replaced itself. Pay-as-you-go pensions depend on the ratio between contributors and beneficiaries, and that ratio only behaves if each generation is roughly the size of the last. Family allowances, child benefits, public housing and universal healthcare were all costed against a fertility rate near three children per woman.
Then fertility fell, everywhere, and kept falling. By the 1980s European rates were below replacement. By the 1990s they were below 1.5 in the south. The systems kept paying, because the cohorts entering work were still large enough to cover the cohorts leaving it. Nobody rewrote the design. The arithmetic was allowed to drift for forty years on the strength of an accident of timing.
The result is the position Europe occupies today. It has a welfare architecture built for a growing population, a labour market that has absorbed tens of millions of people born elsewhere, and an immigration regime assembled piece by piece in response to emergencies rather than designed. Spain, whose fertility rate now sits near 1.10 and whose share of residents born abroad reached 19.3% in 2025, is the clearest illustration. In 1996 that share was 1.4%.
With the recruitment channel closed, asylum became the main legal route into Europe, and it was never intended to be.
Through the 1980s the numbers stayed modest. Then the Soviet bloc dissolved. Germany absorbed roughly 4.5 million ethnic Germans from Eastern Europe and the USSR between 1950 and 2004, with a heavy concentration in the early 1990s, and simultaneously took in several hundred thousand people fleeing the Yugoslav wars. Asylum applications peaked at 438,191 in 1992. Bonn responded in 1993 by amending Article 16a of the Basic Law, introducing the safe third country principle, and the numbers fell by two-thirds within a year.
The same period produced the two agreements that still shape everything: Schengen, implemented from 1995, which thinned internal borders, and the Dublin Convention, in force from 1997, which assigned responsibility for an asylum claim to the first member state the applicant reached. Together they created a system in which the country of first entry carries the cost, and in which a person’s fate depends heavily on which coastline they happen to touch.
Enlargement then redrew the labour map. Twelve countries joined in 2004 and 2007, and free movement turned migration into an intra-European phenomenon for a while. Britain, Ireland and Sweden opened their labour markets immediately; the others imposed transitional controls. By the end of the decade, around a million Polish citizens were living in the United Kingdom, and the EU’s internal mobility was doing more demographic work than anything arriving from outside.
The 2008 financial crisis reversed the flow briefly, pushing southern Europeans north and east. Recovery restored it. Then came 2011, when the Arab Spring toppled governments in Tunis and Cairo and a civil war destroyed Libya, whose coastline had been the Mediterranean’s effective border post. With Libyan patrols gone, the central route opened.
Italy launched Mare Nostrum in October 2013 after 368 people drowned off Lampedusa, ran it for a year at a cost of roughly €9 million a month, then handed responsibility to Frontex’s smaller Operation Triton. Arrivals climbed. In 2015, more than a million people crossed the Mediterranean and the EU registered over 1.2 million first-time asylum applications, with Germany alone receiving 476,649 and Sweden 162,450 — the highest per capita in the Union.
Angela Merkel’s decision that August, captured in the phrase Wir schaffen das, was less a policy than a suspension of enforcement. Germany stopped turning back Syrian applicants. Hungary built a fence. The relocation scheme agreed in September promised to move 160,000 people across the Union and managed around a third of that. In March 2016 the EU–Turkey statement traded money and visa liberalisation for Turkish control of the Aegean, and the numbers fell almost immediately.
What followed was a decade of hardening. Austria, Denmark and Sweden tightened. Italy’s 2017 deal with Libyan militias cut central Mediterranean departures. The pandemic closed borders in 2020, then reopening produced a rebound. Afghanistan fell in August 2021. Russia invaded Ukraine in 2022 and the Union activated temporary protection for the first time, registering millions. Germany recorded net immigration of 1,462,000 that year, a record. Britain’s net migration hit 764,000, also a record, and its politics convulsed.
Through all of it, the funding grew. Frontex’s budget went from €143 million in 2015 to €1.12 billion for 2025. The Pact on Migration and Asylum, adopted in April 2024 and applying from mid-2026, replaced a patchwork with a common framework and — in the proposed 2028–2034 budget — a tripled envelope of €81 billion for migration, border management and internal security.
And in 2024 the western African route to the Canaries broke every record, with 46,843 arrivals in the archipelago and 63,970 across Spain. Then, in 2025, it fell by roughly 62% to about 17,500. The boats had stopped. The institutions had not.
The demographic figures are the part of this story that cannot be negotiated.
On 1 January 2025 the Union held 450.6 million residents. More than a fifth of them, 22.0%, were over sixty-five. Half the population was older than 44.9 years. Eurostat puts the total fertility rate at 1.34 live births per woman for 2024, down from 1.38 and the lowest reading since the series began in 2001. In that year 3.55 million babies were born and 4.82 million people died. Natural decline has been continuous since 2012.
Eurostat’s EUROPOP2025 projection, published in April 2026, carries that forward. The population peaks around 2029 at 453.3 million, eases to 445.0 million by 2050, and ends the century at 398.8 million. Between 2025 and 2100 the scenario anticipates 409.8 million deaths against 253.0 million births, a shortfall of 156.7 million, offset by an assumed 103.7 million net arrivals. Adults aged 20 to 64 fall by 64.9 million. Pensioners rise by 34.8 million. The old-age dependency ratio nearly doubles.
None of this is a prophecy. Eurostat calls its work a what-if scenario and warns that fertility is volatile across eighty years. The near term, however, is already sealed: everyone who will draw a pension in 2050 has been born.
Why fertility collapsed this far is genuinely unresolved. Housing costs crowd out family formation. Childcare provision lagged women’s entry into paid work. The direct cost of raising a child rose faster than median wages for three decades. Urban living compresses space. Each explains a slice, and none accounts for a decline this uniform across economies as different as Finland’s and Portugal’s.
The effect on pensions, though, is mechanical. Pay-as-you-go systems collect from today’s workers and pay today’s retirees, and the ratio between the two deteriorates annually. Governments hold three levers — raise the retirement age, cut the replacement rate, raise contributions — and each has been pulled somewhat over two decades without closing the gap. That is how importing working-age taxpayers became the default rather than a choice.
There is a trap inside that default, and it is worth stating plainly. Immigration delays ageing without reversing it. Migrants age. Their fertility converges downward within a generation, as it has done everywhere. The gap closed in 2035 reopens by 2060, and reopens wider, because the base beneath it has grown. Any policy built on the assumption that arrivals solve the pension problem permanently is built on a treadmill.
None of that explains how a route becomes an institution.
Frontex counted just over 239,000 irregular crossings at the Union’s external borders in 2024, a fall of 38% and the lowest since 2021. Other routes contracted while the western African corridor expanded. Nouadhibou, on a long peninsula on the Atlantic edge of the Sahara some 800 kilometres from the nearest Canary Island, has been the main launch point since 2006.
Conditions at the bottom of that market are harsher than the European debate usually admits. A local source tells the film-makers that young women are raped and held, in his words, like slaves, while captors telephone families to demand ransom. Pressed on whether criminals or police carry out the practice, he names both, saying officers work alongside the smugglers. Weapons and drugs travel with the passengers, who serve as cover. This is one man’s testimony, and the film does not resolve it further.
A short distance away stands a support centre run by OAMR, a Mauritanian organisation working alongside the UN’s International Organization for Migration. A project banner on the wall — “Projet Julia Taft – Phase II” — lists training, outreach and assistance, with the funder named as the United States embassy. Staff confirm that Washington also covers the bakery and the computer room. The Julia Taft Refugee Fund is a State Department programme created in 2000, letting American embassies issue small grants directly to local charities; the Nouakchott call in 2022 offered up to $50,000 per project. The first institution a west African traveller meets on the road to Europe is already a donor project, financed from a third continent.
Caminando Fronteras, a Spanish monitoring group, recorded 10,457 deaths and disappearances among people attempting to reach Spain in 2024, of which 9,757 occurred on the Atlantic crossing. Those are estimates rather than registrations, since the ocean keeps no record, and they should be read as lower bounds.
On arrival, the machinery becomes visible and expensive. Reception on the islands has become one of the costliest per-capita operations in Spanish public administration, with emergency facilities rising from €54.8 million in 2022 to €143.6 million in 2024, according to figures supplied to the European Committee of the Regions. More than 4,500 unaccompanied minors were held at the peak, and Madrid pledged €100 million before adopting a decree to redistribute children across the mainland. Minors are the costly category: they hold a right to care and schooling, cannot be removed quickly, and frequently leave the institutions assigned to them because the debts financing their passage demand wages.
The money behind all of this is layered and largely retrospective. Spain received €43.2 million in 2020 for the Canary situation, €14 million from the European Regional Development Fund, €20 million in humanitarian aid, €100 million earmarked for minors, and a €500 million envelope for migration costs with €20 million ring-fenced for the archipelago. Accem, formally the Asociación Comisión Católica Española de Migración, declared income of €225,118,355.31 in 2024, of which 88.16% came from the central administration. Its work is concrete: lifting arrivals off the islands, housing them in camps, paying a monthly allowance, flying hundreds at a time from Gran Canaria to Madrid.
Most reception finance works by reimbursement. A region or a charity incurs costs, documents them, and is paid back against an agreed tariff, usually per place occupied or per person processed. That is standard public finance and it has one predictable property: costs drive revenue. An empty centre earns less than a full one. Where funding keys off occupancy, a falling caseload becomes a revenue problem, and officials who want their budgets intact acquire a reason to prefer that arrivals continue at a manageable pace.
How much of the total actually works this way is less clear than the headline figures suggest. Some programmes reimburse actual costs, some pay a flat rate per head, some allocate by capacity regardless of use, and some mix all three. Accem’s 88% describes one organisation, not a sector. Germany’s federal refugee costs sit on a separate ledger from Länder and municipal spending. Frontex’s budget is not reimbursement at all, and its crossings fell 38% in the same year its funding rose — which cuts against any simple story about volume maximisation. Nobody can honestly add these numbers together and call the sum a European migration cost.
So the UN official’s reading, that Spain has a financial interest in letting boats keep coming, is plausible and partly demonstrated rather than proven. The test would be a comparison of Canary reception budgets before and after the 2025 collapse in arrivals. That comparison is available, and on the evidence assembled here it has not been settled.
At the French frontier in Irun, a volunteer group has painted a trail of footprints along the pavement, steering people past police checkpoints and into France, where a municipal shelter takes in those without papers. Between the Spanish and French systems sits a gap where documentation runs out and jurisdiction thins, and paint bridges it. Nobody legislated for the footprints. Someone noticed the hole and filled it, which is a fair description of how most of this architecture came to exist.
Germany’s finance ministry put federal spending on refugee and migration at €24.8 billion in 2025, down from €28 billion the year before and €29.6 billion in 2023. Those are federal figures only. The Länder and municipalities carry substantial additional cost, and the federal tier alone has absorbed something near €20 billion a year since 2016. Brussels, meanwhile, is scaling up: the 2028–2034 proposal triples the migration, borders and security envelope to €81 billion, with €15.4 billion for border management and €2.28 billion for the asylum agency against €1.36 billion today.
Money also leaves. Remittances to sub-Saharan Africa reached $56 billion in 2024 by World Bank count, with the continent as a whole receiving more than $95 billion and low- and middle-income countries collectively taking $685 billion — more than foreign direct investment and official development assistance combined.
Beyond the treasury sits the slower bill, paid in services and social capacity. Composition decides most of it. Sweden’s population of immigrant background reached 27.7% in 2025, against 14.5% in 2000; Germany counts 25.2 million residents with a migration background, 30.2% of the total; France records the same share. Second-generation outcomes in education and employment typically beat first-generation ones, so the picture is not one of failure. It is one of gaps that narrow slowly and unevenly.
Crime statistics are where those gaps get misread most often, largely because the denominators differ. Swedish figures from the national council Brå put the likelihood of appearing as a suspect at 3.2% for people born to two Swedish parents, 8% for those born abroad, and 10.2% for those born to two non-native parents. Suspect is not the same as convicted, and the second group is not the same as immigrants. Age structure accounts for much of the gap, since immigrants skew young and young men offend more. Sweden also recorded 317 bombings in 2024, more than double the previous year, and has scheduled prison capacity to rise from 9,000 places to 27,000 by 2033.
Housing and wages follow the same pattern of conditional rather than automatic effects. Immigration adds housing demand, particularly in tight markets, but rents also move with construction rates, interest rates, planning rules and household size. Additional labour supply at the low-skill end restrains pay growth when workers are substitutable, but the effect depends on sector, productivity and the demand generated by new residents themselves. Both claims are reasonable hypotheses with real evidence behind them, and both are stated more confidently than the literature supports.
Whether immigration pays for itself has an answer that depends entirely on who arrives, at what age, and what they do. A worker arriving at 25 and leaving at 65 pays four decades of taxes while consuming little in pensions or healthcare. A family arriving with several children, housed socially and receiving transfers, may run a net cost for two decades before turning positive. Someone arriving at 55 and working a decade before drawing a full pension is marginal at best. The aggregate literature generally finds small net effects in either direction, usually within one or two percentage points of GDP. George Borjas, whose work on the subject spans four decades, has been notably unromantic about the size of the prize. “The immigration surplus is small.” — George Borjas
The far end of the corridor is expanding on a scale without precedent. The United Nations projects sub-Saharan Africa growing 79% to 2.2 billion people by 2054 and reaching 3.3 billion by 2100, with nine countries doubling within thirty years. World population should peak near 10.3 billion in the mid-2080s. Europe, meanwhile, is ageing before it has grown rich enough to afford it, and its working-age population shrinks while African labour forces expand by millions a year.
Paul Collier has argued that the binding constraint is not willingness but absorption — the pace at which a host society can turn arrivals into functioning participants rather than a permanent underclass. Speed, on his account, decides whether immigration enriches or corrodes. “Migration is like a bicycle: if it goes too slowly it falls over, if it goes too fast it crashes.” — Paul Collier
Some of the near future is already scheduled. The Pact enters application by mid-2026 and changes procedure rather than volume. The tripled budget begins in 2028. The rest is inference from the published trajectory: the 20-to-64 cohort dips below 255 million by the mid-2030s, the old-age dependency ratio crosses 50% around the same time, the natural deficit peaks above 2.5 million deaths over births in a single decade during the 2055–2064 window, and by 2100 the Union is 53 million smaller with roughly a third of its population over sixty-five.
The instinct that something is being run badly survives contact with the evidence. The further instinct that a single coordinating hand is running it does not, and the material cuts against both the conspiracy reading and the competence reading in roughly equal measure.
Nobody designed the corridor. What exists is a sequence of improvisations that hardened into a system: a labour shortage answered by recruitment, a recruitment stop answered by family reunion, an asylum door opened by accident, a Schengen area that thinned internal borders while Dublin concentrated costs on the periphery, a series of wars that filled the routes, and a funding architecture that pays for activity because activity is easier to measure than outcome. Each step made local sense. The sum was never voted on.
That is why the public argument never resolves. Both sides describe something true. The system is humanitarian in operation and self-perpetuating in structure. It delivers genuine help to genuine people and also delivers revenue to the organisations delivering the help. Neither fact cancels the other, and neither is anybody’s fault.
Two findings complicate the clean version of the incentive story, and both are worth keeping. The Frontex anomaly shows that the enforcement arm is not funded on volume and has no obvious reason to want more boats, so the incentive operates on reception rather than on borders. And the scale problem shows that the corridor generating the loudest political noise is demographically marginal — a small fraction of immigration that happens mostly through quiet legal channels.
So the conclusion is narrower than the documentary’s framing and more useful. Reception funding rewards activity, which creates a mild structural preference for continued arrivals. Border funding does not. The demographic pressure underneath both is real, arithmetic and slow, and it will not respond to any single reform. What remains unproven is whether the incentive actually changes decisions at the margin, and settling that requires documents rather than argument.
A short list of questions follows for a citizen rather than a verdict. What is the funding tied to — heads, places, outcomes or costs? Does the allocation fall automatically when the caseload falls, or only after a renegotiation? Who signs the renewal, and against what evidence of performance? Which budget line grew while arrivals dropped, and why?
Those questions have answers, and they are dull, technical and largely public. Nobody has to be lying for them to be uncomfortable.
Europe will not be replaced by immigration in any literal sense, and it will not be rescued by it either. It will be reshaped by it, expensively and unevenly, along lines the projections already sketch. Sixty years of decisions made one emergency at a time produced a system nobody chose and few understand, and it is now large enough to shape the continent’s future more than any government that inherits it. The boats will speed up and slow down. The arithmetic underneath will keep its own schedule.

How Europe invited workers, promised itself they would leave, and built a welfare state on the assumption that they had
The story starts with a labour shortage and a confidence that turned out to be misplaced.
Postwar reconstruction ran on manpower. West Germany’s economy expanded faster than its workforce, and from 1955 onwards Bonn signed a series of bilateral agreements to import labour: Italy first, then Greece and Spain in 1960, Turkey in 1961, Morocco in 1963, Portugal in 1964, Tunisia in 1965, Yugoslavia in 1968. France ran its own recruitment through the Office National d’Immigration. The Netherlands brought in Moroccans and Turks. Belgium signed agreements in 1964. Sweden recruited Finns, Greeks and Yugoslavs.

By 1973 the Federal Republic hosted roughly four million foreigners, of whom some 2.6 million were in work. Then the first oil shock hit, unemployment rose, and on 23 November 1973 Bonn stopped recruiting. France followed the following year.
Rotation ended that day, and almost nobody noticed for a decade. Workers already inside Germany faced a choice between leaving permanently and bringing their families, and they overwhelmingly chose the second. Spouses arrived under family reunion provisions, children followed, and by the early 1980s it was clear that the guest workers had become settlers. The same pattern repeated in France, the Low Countries and Scandinavia, with variations but no exceptions.
What matters for the present is the assumption buried underneath. Every European welfare state built in the twentieth century — Bismarck’s pension insurance of 1889, Beveridge’s postwar settlement in Britain, the continental systems that followed — assumed a population that replaced itself. Pay-as-you-go pensions depend on the ratio between contributors and beneficiaries, and that ratio only behaves if each generation is roughly the size of the last. Family allowances, child benefits, public housing and universal healthcare were all costed against a fertility rate near three children per woman.
Then fertility fell, everywhere, and kept falling. By the 1980s European rates were below replacement. By the 1990s they were below 1.5 in the south. The systems kept paying, because the cohorts entering work were still large enough to cover the cohorts leaving it. Nobody rewrote the design.

In March 2016 the EU–Turkey statement traded money and visa liberalisation for Turkish control of the Aegean, and the numbers fell almost immediately.
What followed was a decade of hardening. Austria, Denmark and Sweden tightened. Italy’s 2017 deal with Libyan militias cut central Mediterranean departures. The pandemic closed borders in 2020, then reopening produced a rebound. Afghanistan fell in August 2021. Russia invaded Ukraine in 2022 and the Union activated temporary protection for the first time, registering millions. Germany recorded net immigration of 1,462,000 that year, a record. Britain’s net migration hit 764,000, also a record, and its politics convulsed.
Through all of it, the funding grew. Frontex’s budget went from €143 million in 2015 to €1.12 billion for 2025. The Pact on Migration and Asylum, adopted in April 2024 and applying from mid-2026, replaced a patchwork with a common framework and — in the proposed 2028–2034 budget — a tripled envelope of €81 billion for migration, border management and internal security.
And in 2024 the western African route to the Canaries broke every record, with 46,843 arrivals in the archipelago and 63,970 across Spain. Then, in 2025, it fell by roughly 62% to about 17,500. The boats had stopped. The institutions had not.
What the arithmetic was never designed to survive
The demographic figures are the part of this story that cannot be negotiated.
On 1 January 2025 the Union held 450.6 million residents. More than a fifth of them, 22.0%, were over sixty-five. Half the population was older than 44.9 years. Eurostat puts the total fertility rate at 1.34 live births per woman for 2024, down from 1.38 and the lowest reading since the series began in 2001. In that year 3.55 million babies were born and 4.82 million people died. Natural decline has been continuous since 2012.
Eurostat’s EUROPOP2025 projection, published in April 2026, carries that forward. The population peaks around 2029 at 453.3 million, eases to 445.0 million by 2050, and ends the century at 398.8 million. Between 2025 and 2100 the scenario anticipates 409.8 million deaths against 253.0 million births, a shortfall of 156.7 million, offset by an assumed 103.7 million net arrivals. Adults aged 20 to 64 fall by 64.9 million. Pensioners rise by 34.8 million. The old-age dependency ratio nearly doubles.

None of this is a prophecy. Eurostat calls its work a what-if scenario and warns that fertility is volatile across eighty years. The near term, however, is already sealed: everyone who will draw a pension in 2050 has been born.
Why fertility collapsed this far is genuinely unresolved. Housing costs crowd out family formation. Childcare provision lagged women’s entry into paid work. The direct cost of raising a child rose faster than median wages for three decades. Urban living compresses space. Each explains a slice, and none accounts for a decline this uniform across economies as different as Finland’s and Portugal’s.
The effect on pensions, though, is mechanical. Pay-as-you-go systems collect from today’s workers and pay today’s retirees, and the ratio between the two deteriorates annually. Governments hold three levers — raise the retirement age, cut the replacement rate, raise contributions — and each has been pulled somewhat over two decades without closing the gap. That is how importing working-age taxpayers became the default rather than a choice.
There is a trap inside that default, and it is worth stating plainly. Immigration delays ageing without reversing it. Migrants age. Their fertility converges downward within a generation, as it has done everywhere. The gap closed in 2035 reopens by 2060, and reopens wider, because the base beneath it has grown. Any policy built on the assumption that arrivals solve the pension problem permanently is built on a treadmill.
A corridor assembles itself, from a Mauritanian harbour to a painted trail in the Basque Country
None of that explains how a route becomes an institution.
Frontex counted just over 239,000 irregular crossings at the Union’s external borders in 2024, a fall of 38% and the lowest since 2021. Other routes contracted while the western African corridor expanded. Nouadhibou, on a long peninsula on the Atlantic edge of the Sahara some 800 kilometres from the nearest Canary Island, has been the main launch point since 2006.
Conditions at the bottom of that market are harsher than the European debate usually admits. A local source tells the film-makers that young women are raped and held, in his words, like slaves, while captors telephone families to demand ransom. Pressed on whether criminals or police carry out the practice, he names both, saying officers work alongside the smugglers. Weapons and drugs travel with the passengers, who serve as cover. This is one man’s testimony, and the film does not resolve it further.
A short distance away stands a support centre run by OAMR, a Mauritanian organisation working alongside the UN’s International Organization for Migration. A project banner on the wall — “Projet Julia Taft – Phase II” — lists training, outreach and assistance, with the funder named as the United States embassy. Staff confirm that Washington also covers the bakery and the computer room. The Julia Taft Refugee Fund is a State Department programme created in 2000, letting American embassies issue small grants directly to local charities; the Nouakchott call in 2022 offered up to $50,000 per project. The first institution a west African traveller meets on the road to Europe is already a donor project, financed from a third continent.

Caminando Fronteras, a Spanish monitoring group, recorded 10,457 deaths and disappearances among people attempting to reach Spain in 2024, of which 9,757 occurred on the Atlantic crossing. Those are estimates rather than registrations, since the ocean keeps no record, and they should be read as lower bounds.
On arrival, the machinery becomes visible and expensive. Reception on the islands has become one of the costliest per-capita operations in Spanish public administration, with emergency facilities rising from €54.8 million in 2022 to €143.6 million in 2024, according to figures supplied to the European Committee of the Regions. More than 4,500 unaccompanied minors were held at the peak, and Madrid pledged €100 million before adopting a decree to redistribute children across the mainland. Minors are the costly category: they hold a right to care and schooling, cannot be removed quickly, and frequently leave the institutions assigned to them because the debts financing their passage demand wages.
The money behind all of this is layered and largely retrospective. Spain received €43.2 million in 2020 for the Canary situation, €14 million from the European Regional Development Fund, €20 million in humanitarian aid, €100 million earmarked for minors, and a €500 million envelope for migration costs with €20 million ring-fenced for the archipelago. Accem, formally the Asociación Comisión Católica Española de Migración, declared income of €225,118,355.31 in 2024, of which 88.16% came from the central administration. Its work is concrete: lifting arrivals off the islands, housing them in camps, paying a monthly allowance, flying hundreds at a time from Gran Canaria to Madrid.
Most reception finance works by reimbursement. A region or a charity incurs costs, documents them, and is paid back against an agreed tariff, usually per place occupied or per person processed. That is standard public finance and it has one predictable property: costs drive revenue. An empty centre earns less than a full one. Where funding keys off occupancy, a falling caseload becomes a revenue problem, and officials who want their budgets intact acquire a reason to prefer that arrivals continue at a manageable pace.
How much of the total actually works this way is less clear than the headline figures suggest. Some programmes reimburse actual costs, some pay a flat rate per head, some allocate by capacity regardless of use, and some mix all three. Accem’s 88% describes one organisation, not a sector. Germany’s federal refugee costs sit on a separate ledger from Länder and municipal spending. Frontex’s budget is not reimbursement at all, and its crossings fell 38% in the same year its funding rose — which cuts against any simple story about volume maximisation. Nobody can honestly add these numbers together and call the sum a European migration cost.
So the UN official’s reading, that Spain has a financial interest in letting boats keep coming, is plausible and partly demonstrated rather than proven. The test would be a comparison of Canary reception budgets before and after the 2025 collapse in arrivals. That comparison is available, and on the evidence assembled here it has not been settled.
At the French frontier in Irun, a volunteer group has painted a trail of footprints along the pavement, steering people past police checkpoints and into France, where a municipal shelter takes in those without papers. Between the Spanish and French systems sits a gap where documentation runs out and jurisdiction thins, and paint bridges it. Nobody legislated for the footprints. Someone noticed the hole and filled it, which is a fair description of how most of this architecture came to exist.
Money follows people, and the bill is still being written
Germany’s finance ministry put federal spending on refugee and migration at €24.8 billion in 2025, down from €28 billion the year before and €29.6 billion in 2023. Those are federal figures only. The Länder and municipalities carry substantial additional cost, and the federal tier alone has absorbed something near €20 billion a year since 2016. Brussels, meanwhile, is scaling up: the 2028–2034 proposal triples the migration, borders and security envelope to €81 billion, with €15.4 billion for border management and €2.28 billion for the asylum agency against €1.36 billion today.

Money also leaves. Remittances to sub-Saharan Africa reached $56 billion in 2024 by World Bank count, with the continent as a whole receiving more than $95 billion and low- and middle-income countries collectively taking $685 billion — more than foreign direct investment and official development assistance combined.
Beyond the treasury sits the slower bill, paid in services and social capacity. Composition decides most of it. Sweden’s population of immigrant background reached 27.7% in 2025, against 14.5% in 2000; Germany counts 25.2 million residents with a migration background, 30.2% of the total; France records the same share. Second-generation outcomes in education and employment typically beat first-generation ones, so the picture is not one of failure. It is one of gaps that narrow slowly and unevenly.
Crime statistics are where those gaps get misread most often, largely because the denominators differ. Swedish figures from the national council Brå put the likelihood of appearing as a suspect at 3.2% for people born to two Swedish parents, 8% for those born abroad, and 10.2% for those born to two non-native parents. Suspect is not the same as convicted, and the second group is not the same as immigrants. Age structure accounts for much of the gap, since immigrants skew young and young men offend more. Sweden also recorded 317 bombings in 2024, more than double the previous year, and has scheduled prison capacity to rise from 9,000 places to 27,000 by 2033.
Housing and wages follow the same pattern of conditional rather than automatic effects. Immigration adds housing demand, particularly in tight markets, but rents also move with construction rates, interest rates, planning rules and household size. Additional labour supply at the low-skill end restrains pay growth when workers are substitutable, but the effect depends on sector, productivity and the demand generated by new residents themselves. Both claims are reasonable hypotheses with real evidence behind them, and both are stated more confidently than the literature supports.
Whether immigration pays for itself has an answer that depends entirely on who arrives, at what age, and what they do. A worker arriving at 25 and leaving at 65 pays four decades of taxes while consuming little in pensions or healthcare. A family arriving with several children, housed socially and receiving transfers, may run a net cost for two decades before turning positive. Someone arriving at 55 and working a decade before drawing a full pension is marginal at best. The aggregate literature generally finds small net effects in either direction, usually within one or two percentage points of GDP. George Borjas, whose work on the subject spans four decades, has been notably unromantic about the size of the prize. “The immigration surplus is small.” — George Borjas

The far end of the corridor is expanding on a scale without precedent. The United Nations projects sub-Saharan Africa growing 79% to 2.2 billion people by 2054 and reaching 3.3 billion by 2100, with nine countries doubling within thirty years. World population should peak near 10.3 billion in the mid-2080s. Europe, meanwhile, is ageing before it has grown rich enough to afford it, and its working-age population shrinks while African labour forces expand by millions a year.
Paul Collier has argued that the binding constraint is not willingness but absorption — the pace at which a host society can turn arrivals into functioning participants rather than a permanent underclass. Speed, on his account, decides whether immigration enriches or corrodes. “Migration is like a bicycle: if it goes too slowly it falls over, if it goes too fast it crashes.” — Paul Collier
Some of the near future is already scheduled. The Pact enters application by mid-2026 and changes procedure rather than volume. The tripled budget begins in 2028. The rest is inference from the published trajectory: the 20-to-64 cohort dips below 255 million by the mid-2030s, the old-age dependency ratio crosses 50% around the same time, the natural deficit peaks above 2.5 million deaths over births in a single decade during the 2055–2064 window, and by 2100 the Union is 53 million smaller with roughly a third of its population over sixty-five.
Where this leaves the argument
The instinct that something is being run badly survives contact with the evidence. The further instinct that a single coordinating hand is running it does not, and the material cuts against both the conspiracy reading and the competence reading in roughly equal measure.
Nobody designed the corridor. What exists is a sequence of improvisations that hardened into a system: a labour shortage answered by recruitment, a recruitment stop answered by family reunion, an asylum door opened by accident, a Schengen area that thinned internal borders while Dublin concentrated costs on the periphery, a series of wars that filled the routes, and a funding architecture that pays for activity because activity is easier to measure than outcome. Each step made local sense. The sum was never voted on.
That is why the public argument never resolves. Both sides describe something true. The system is humanitarian in operation and self-perpetuating in structure. It delivers genuine help to genuine people and also delivers revenue to the organisations delivering the help. Neither fact cancels the other, and neither is anybody’s fault.
Two findings complicate the clean version of the incentive story, and both are worth keeping. The Frontex anomaly shows that the enforcement arm is not funded on volume and has no obvious reason to want more boats, so the incentive operates on reception rather than on borders. And the scale problem shows that the corridor generating the loudest political noise is demographically marginal — a small fraction of immigration that happens mostly through quiet legal channels.
So the conclusion is narrower than the documentary’s framing and more useful. Reception funding rewards activity, which creates a mild structural preference for continued arrivals. Border funding does not. The demographic pressure underneath both is real, arithmetic and slow, and it will not respond to any single reform. What remains unproven is whether the incentive actually changes decisions at the margin, and settling that requires documents rather than argument.
A short list of questions follows for a citizen rather than a verdict. What is the funding tied to — heads, places, outcomes or costs? Does the allocation fall automatically when the caseload falls, or only after a renegotiation? Who signs the renewal, and against what evidence of performance? Which budget line grew while arrivals dropped, and why?
Those questions have answers, and they are dull, technical and largely public. Nobody has to be lying for them to be uncomfortable.
Europe will not be replaced by immigration in any literal sense, and it will not be rescued by it either. It will be reshaped by it, expensively and unevenly, along lines the projections already sketch. Sixty years of decisions made one emergency at a time produced a system nobody chose and few understand, and it is now large enough to shape the continent’s future more than any government that inherits it. The boats will speed up and slow down. The arithmetic underneath will keep its own schedule.
