You’ve been told the fertility crisis is about avocado toast, student loans, or Netflix. But look closer. The real reason fewer people are having kids is sitting right there in your paycheck—the deduction labeled ‘pension’.
Here’s the uncomfortable truth that no politician will say out loud: The state pension didn’t just promise to take care of the elderly—it promised to take care of them without needing children. That promise is now costing us our future.
Think about it. For most of human history, children were your retirement plan. You raised them, they supported you when you got old. It was a biological and economic contract. Then came the modern welfare state. Pay-as-you-go pensions meant you could hand your money to the government, and the government would hand it back to you when you retired—courtesy of the next generation. Suddenly, children became optional. Even worse, they became expensive. The state had replaced them.
I saw this firsthand in Japan. Tokyo’s streets are filled with the elderly, while the country’s birthrate sinks to 1.2. The pension system is generous, the elderly vote in droves, and every attempt to reform it is met with fury. The result? A demographic black hole. The same pattern repeats in Italy, South Korea, and increasingly in Germany.
Every politician knows the fix. None of them will touch it. Because the people who benefit most from the current system—the retired and soon-to-retire—are also the most reliable voters. Cutting pensions to boost fertility is politically suicide. So the trap tightens: the more protected the pension, the fewer babies are born, and the fewer workers there are to fund the pensions of the future.
Let that sink in. The comfortable retiree voting to protect their benefits is voting to reduce the number of grandchildren who will one day support them. It’s a slow-motion self-destruction, wrapped in the language of ‘entitlement’ and ‘security’.
You might think this is just a problem for old people. It’s not. If you’re under 40, you’re paying into a system that assumes a steady stream of future workers. But that stream is drying up. Every dollar you put into your pension today is a bet on someone else’s baby. If fewer babies are born, that bet fails. Your retirement benefits are not guaranteed—they’re a promise that depends on births you can’t control.
So the next time you hear about a fertility crisis, don’t blame Netflix or avocado toast. Blame the pension system that made children optional. Then ask yourself: what are you willing to sacrifice to fix it?
Because the alternative is to keep pretending that a system designed to care for the old can survive without the young. And that’s a lie that will eventually bankrupt us all.
FAQ
Q: Isn't this just correlation? Maybe low fertility is due to other factors like housing costs or culture.
A: There's strong evidence from cross-country comparisons that pay-as-you-go pensions reduce fertility. The mechanism is clear: when the state provides for old age, children become an economic liability rather than an asset. The correlation holds even after controlling for income, education, and urbanization. The pension is a structural cause, not just a correlation.
Q: So what's the practical implication? Should I stop saving for retirement?
A: No, but you should be aware that your future pension benefits depend on future births. If you're young, advocate for policies that support families, not just pensions—like paid parental leave, childcare subsidies, and tax credits for children. If you're retired, recognize that protecting your benefits at all costs is harming your grandchildren. The fix requires a generational bargain, not a blind defense of the status quo.
Q: Isn't it better to have a pension system than to rely on children? That's progress.
A: Yes, in principle. But the problem is that the current system is unsustainable. The contrarian view is that we need to rethink the entire social contract—perhaps decouple retirement from the pay-as-you-go model, introduce fertility incentives within the pension system, or move toward a funded system that doesn't depend on the next generation. The current system is a trap, not a solution. Progress is about designing systems that work long-term, not just for the current voter.
