Why Spain’s Economy Cannot Survive Without Immigrants

Who sustains pensions if newcomers leave?

Europe does not fully measure how much it needs its existing immigrant population. Josep Borrell stated this on lasensla Xplica, adding a crucial question: what would happen if they actually left? He referred to immigrants as "emigrants"—a slip or intentional nod depending on interpretation—and sparked a debate far beyond a single phrase. The short answer is that no one has the full picture. The long answer breaks down into parts, almost all supported by numbers.

The demographic hole the pyramid cannot close

The starting point is arithmetic. An aging population must either add new contributors or raise the retirement age. There is no third way. It is recalled that Spain had 27 million inhabitants in 1945, fresh from a civil war with about 500,000 deaths among military-age men, yet the country did not collapse. True. The nuance is that the population pyramid was wide at the base then. Today, it resembles a vase. Each retiree leaving the system leaves fewer shoulders to support them, and native birth rates alone do not compensate. Hence the cynical summary circulating: immigration and pensions are the same issue, and those who come after must deal with it. Short-termism par excellence, signed by a generation that will not be around to see the consequences.

Housing and wages: where the market squeezes

The most repeated objection targets aggregate effects rather than individuals. If many people arrive and housing supply remains static, rents rise. If many enter the same wage bracket, bargaining power weakens. This argument suggests migratory pressure hits hardest those already competing for apartments and salaries, specifically those born since 2000. Opposing this is another view: some sectors simply cannot operate without foreign labor. And a sardonic derivative circulates: if these businesses close when workers leave, perhaps the problem was not who arrived, but a model that only fits with poverty wages.

The fiscal balance, an account no one closes

It is argued that certain migration flows cost more in services and benefits than they contribute, with the imbalance paid by ordinary taxpayers. The counterargument is that the picture changes depending on whether short or long term is measured, and the same could be said of a native retiree: they pay little tax and consume healthcare and pensions. The problem with this section is that the complete breakdown—social contributions, consumption, indirect taxes, allocated public spending—is rarely provided. Without that breakdown, discussions remain based on impressions.

The mirror: Japan, China, and the robotic path

Then appears the alternative that dissolves the entire dilemma. Japan, older than Europe, has relied on technology instead of human replacement. China grows with barely any immigration. Poland is cited as a case Brussels should not tolerate. The thesis: with robotics and AI, the same production output is achieved with fewer people, shifting the issue from demographics to distribution. The common-sense objection: a robot does not pay social security, does not consume, and does not pay rent. Automating without consumers empties factories; it does not fill them.

What the headline does not resolve

Borrell's statement is easy to attack and difficult to refute with data, because both truths coexist: without replacement, the system strains, and with poorly managed replacement, those already present become resentful. That is the trap. The uncomfortable part—who captures the benefit of arriving labor, and at what wage cost—is excluded from nearly all headlines. And there, exactly there, the analysis stalls.
