Pensions and baby boomers: the demographic arithmetic nobody wants to see
The ratio of contributors per pensioner has gone from four to one to practically one to one. The baby boom generation – born between the mid-forties and mid-sixties – is retiring en masse, while the base of active workers is shrinking due to falling birth rates, accelerated after the legalization of the contraceptive pill in 1975 in Spain. The pay-as-you-go system, designed for an expansive population pyramid, faces a structural inversion that no political patch can solve. The numbers don't add up, and yet the public debate keeps avoiding the only variable that can actually balance them: inflation.
The forgotten factor: the contraceptive pill
The origin of the problem is not ideological, but demographic. The pill, approved in the U.S. in 1960 and in Spain after Franco's death, broke the trend of large families. The daughters of the baby boomers did not have children like their mothers did, and without demographic consequences. The age pyramid shows a brutal cut: the last boomers were born in 1965, are now turning 60, will retire in five years and live another 25. Pension spending will grow for at least twenty more years before stabilizing, when the largest generation disappears. Those who argue that the solution is sarracena – that everyone should live off their savings – run into an arithmetical reality: if the arithmetic doesn't work, there is no fair distribution possible, only disorder.
Inflation at 25%: the taboo solution
Faced with the impossibility of cutting nominal pensions – due to the electoral cost and the risk of social unrest – the only escape valve is inflation. A sustained 25% per year would liquefy the public debt earmarked for pensions, level high benefits down toward the minimums and allow the rest of the budget to be balanced. It is a silent tax on savers, but also the only path that avoids immediate collapse. Against this position, another sector defends an orderly default and a reset of the financial system, trinc by austerity, arguing that prolonged inflation only impoverishes those without assets. However, that solution is technically possible but politically unviable: acknowledging the bankruptcy of the pension system would be signing the death sentence of the political class that has perpetuated it.
The fallacy of demographic recomposition
Some analyses point out that, in about 25 years, the pyramid will recompose itself once the boomers disappear. But that horizon clashes with another reality: the population that will take their place is not the same. Immigration over recent decades has brought in millions of people with different demographic and cultural patterns, who do not always integrate into the contributory system. Although there is talk of expelling parasites and cutting social spending, the second and third generations of immigrants are already nationals who cannot be expelled. The economy will be cleaned up by pure demographics, but the social fabric that sustains it will be unrecognizable.
The silent tax is already here
While the debate revolves around drastic options, the State is already applying its own adjustment mechanism: the tax-free allowance of the IRPF (Spain's personal income tax) has remained at 5,550 euros since 2007, without being adjusted for the accumulated real inflation of around 10% per year. This means extra revenue that goes toward plugging holes, including the pension gap. But it is not a solution, only a postponement. The question nobody answers is how long the fiction can be maintained before arithmetic imposes itself by force.
