PARIS -- For decades, Europeans have been happy to surrender around half of their pay to the state. In exchange, they could expect to retire in their 60s on a relatively comfortable, state-funded pension.
No longer. Stretched public finances and a rapidly aging population are threatening this covenant, stoking fear and anger across the continent over the future of a cradle-to-grave welfare state voters had long taken for granted.
The outrage is particularly sharp in France, where employees have generally been able to retire at 62 with a tax-funded pension based on their past salary -- a promise the cash-strapped, overindebted government is struggling to honor.
Concern about the sustainability of France's welfare state has been a key driver of the protests that have shaken the country in recent weeks. It is also calling into question the tacit generational contract under which younger workers pay for their elders' retirement.
After losing her finance job in December, Marie Caron, 61, is worried for the first time about how she will get by in old age. She can only start collecting retirement benefits at 63 -- or 66 to qualify for get a full pension -- so she will have to find a new job before she retires, a difficult prospect in France's rigid labor market where recruiters rarely hire older workers. Seven job interviews this year have produced nothing.
"I've paid a huge amount into the system and should be entitled to a decent pension," Caron said. "Instead, I might end up on the streets."
While American workers have long managed their own retirement portfolios to supplement a baseline Social Security check, continental Europeans were promised a comprehensive, state-guaranteed income for life.
Their pension systems are mostly pay-as-you-go, meaning that benefits are funded directly by payroll taxes. As the postwar baby boom generation enters its 80s, there aren't enough workers around to pay for their elders' pensions, forcing governments to consume an ever-larger portion of national budgets to meet retirees' entitlements.
This in turn is driving up sovereign debt and borrowing costs, and crowding out investments in defense, infrastructure and education.
French voters enjoy both one of the world's longest life expectancies and some of its earliest statutory retirement ages. Reaching pension age in the country is widely considered a rite of passage into a second phase of life dedicated to travel, hobbies and leisure that, for the luckiest, can stretch well into three decades. As a result, voters have fiercely resisted government policies designed to make them work longer.
A recent government report revealed that roughly one-third of the Education Ministry's budget is siphoned off to cover pension checks for former civil servants. At the Interior Ministry, which oversees policing, pensions absorb 30% of total departmental spending.
France's public debt has climbed to 3.6 trillion euros this year, equivalent to $4 trillion, up from EUR2.2 trillion when French President Emmanuel Macron was elected in 2017. The French treasury pays roughly the same interest rate to borrow on 10-year bond markets as Italy, and the government faces intense pressure from financial markets and European Union budget enforcers to pass sweeping spending cuts.
"There is no way France can implement the needed budget consolidation without addressing the widening deficit in the pension system," said Jacob Kirkegaard, a nonresident senior fellow at the Peterson Institute for International Economics in Washington.
In an interview on Wednesday with The Wall Street Journal and other newspapers, French Finance Minister Roland Lescure said raising the nation's legal retirement age -- now between 62 and 64 -- was mathematically unavoidable.
"Demographics is the only science that never lies," Lescure said. "You can't increase the active population 20 years from now if you haven't made the babies today."
Across Europe, governments follow roughly three different models for state-funded pensions.
Countries including France, Italy and Spain rely on pure pay-as-you-go financing. There, state pensions replace between 74% and 82% of previous earnings. Unlike in the U.S., where more than $35 trillion in private retirement assets sits in stocks and bonds, employees' pension insurance contributions flow directly into the pockets of retirees. These contributions exceed 27% of gross wages in France and 33% in Italy.
When borrowing costs surged during the 2010-15 eurozone sovereign-debt crisis, Greece, Italy, Spain and Portugal pushed through some pension cuts. In 2011, Italy lifted its retirement age to 67 and linked it to life expectancy. Spain lengthened the wage history used to calculate payouts. Greece slashed pensions by up to 40%.
France, however, largely stayed put. When Macron pushed a bill progressively raising the retirement age from 62 to 64 in 2023, he had to bypass parliament without a vote, triggering months of street clashes, burned trash heaps and nationwide transit strikes. That reform has since been put on hold.
In a second camp, Northern European countries have developed hybrid models that economists generally see as more sustainable. Denmark, the Netherlands and Sweden combine a basic state pension floor with quasi-mandatory workplace pension plans invested globally. Pension assets in these three countries range from 100% to 200% of gross domestic product. This is comparable to the U.S., but the funds are managed by nonprofit industry trusts that convert accumulated savings into lifetime annuities rather than lump sums.
This model delivers guaranteed income support, high retirement benefits and large pools of risk capital that help build national wealth, Kirkegaard said. But it also requires longer working lives: In Denmark, the retirement age is linked by law to life expectancy and is projected to pass 74 for younger cohorts around 2070.
The third group, comprising Germany and the U.K., sits in the middle. The U.K. runs a low, flat state pension paired with automatic workplace enrollment into private funds. Germany's system is also pay-as-you-go but pensions are substantially lower than in neighboring France, and monthly payments are capped. Germany also uses an automatic formula that slows benefit growth when the contributor-to-retiree ratio worsens.
Despite the comparatively low level of state pensions and a retirement age now set at 67, Berlin still has to spend over EUR110 billion a year to make up the yawning shortfall in the pension system -- the single largest individual item in the state budget and just under a fifth of total federal spending.
A 2023 study by economists Burkhard Heer, Vito Polito and Michael R. Wickens measured "pension space" -- the headroom governments have to fund pensions through labor taxes before hitting revenue-destroying ceilings. While the U.S.'s and U.K.'s stood above 40%, France's and Italy's sat below 10% and were projected to hit zero by 2030. At that point, raising taxes on active workers simply reduces employment and shrinks total receipts.
Switching models is difficult. Prefunding pensions requires decades of steady capital accumulation and can force one generation to pay twice -- for their elders and for their own pensions.
In France, diverting payroll taxes into newly created investment funds today would starve the treasury of the cash to pay current retirees, requiring tens of billions in fresh borrowing for a country whose debt already tops 117% of GDP.
After decades when retirement was considered part of the natural order, many younger voters are beginning to realize the numbers no longer add up.
"To me, it makes no sense to be using a model today that worked for an era that is no longer the same," said Riana Sid-Ahmed, a 19-year-old psychology student in Paris. "I doubt I'll have a pension by the time I retire."
