Pension Crisis: Who's Bearing the Burden?

In the 20th century, pension systems were seen as one of the most important socioeconomic commitments of developed nations.

Workers contribute throughout their careers, and in old age, society-through the state-ensures them a minimum income to sustain their livelihood.

It was not just a welfare policy, but a long-term promise between generations.

The problem is that this promise was built on a completely different demographic backdrop.

When pension systems were created, life expectancy was significantly lower, birth rates were high, and the workforce grew steadily.
Today, those assumptions no longer hold.
- Global life expectancy has risen by about 30 years since 1950
- Fertility rates have steadily declined in nearly every developed economy
- By 2050, 1 in 6 people worldwide will be over 65, up from 1 in 11 today

The result is an increasingly imbalanced equation: fewer workers supporting more retirees.

In the US, the worker-to-retiree ratio has fallen from 16 in the 1950s to under 3 today.
Japan has lost more than 13 million working-age people since the mid-1990s.
In France, pension spending accounts for about 14% of GDP.

→ These figures show the issue is no longer theoretical-it's exerting direct pressure on budgets and fiscal stability.

The World Economic Forum estimates that by 2050, the retirement income gap-between needs and actual accumulated assets-could reach $400 trillion, several times the size of the current global economy.

Yet pension reform remains one of the topics governments are least willing to confront, as every option means people working longer, contributing more, or accepting less.
