The Treasury has been warned that Britain’s youngest workers are already planning for a retirement without the state pension, as a demographic time bomb threatens to hollow out the nation’s social safety net. According to a confidential briefing circulated among senior officials, the combination of an ageing population, falling birth rates, and a shrinking tax base means that by the time Generation Z reaches pension age, the current system may be unsustainable.
For young people like 24-year-old Manchester warehouse worker Chloe Davies, the warning is no surprise. She has already given up on the state pension. “I don’t see how it can still exist when I’m in my sixties. The government is constantly moving the goalposts: raising the age, cutting entitlements. My grandparents got theirs at 65. My parents are looking at 68. I’m planning for 70 or never.”
Chloe is far from alone. A survey by the Resolution Foundation found that 6 in 10 18-to-30-year-olds do not expect to receive a full state pension. Many are adjusting their finances accordingly. The number of under-30s opening private pensions has surged 30% since 2019, while lifetime ISA accounts, designed for first-time buyers but also used for retirement, have become popular among young savers.
But for the vast majority of Gen Z workers, the option to save is a luxury. Renting takes a huge share of wages. The cost of food and energy has squeezed budgets. Many cannot afford to put money aside. “I’d love to start a pension, but my monthly rent is £900. That’s more than half my take-home pay. After bills and food, there’s nothing left,” says 22-year-old barista Liam O’Connor from Leeds.
The Treasury briefing, leaked to the Financial Times, paints a stark picture: by 2050, the ratio of workers to pensioners will fall from 3.3 to 1 to just 2.3 to 1. The National Insurance contributions that currently fund pensions, alongside general taxation, will cover only 70% of the projected bill. “The maths simply does not add up,” the briefing states. “Without reform, either benefits will have to be slashed or taxes raised significantly.”
The response from the government has been cautious. A Treasury spokesperson insisted they are “committed to the triple lock that protects the state pension.” But the triple lock itself is under pressure. It guarantees pension rises by the highest of inflation, earnings growth, or 2.5%, which has already pushed spending to record levels. In 2023, it cost taxpayers £124 billion.
This demographic crisis disproportionately affects the regions and the working class. In the North, where life expectancy is lower but pension ages are uniform, many workers are already dying before they receive their full entitlement. The gap between life expectancy in the richest and poorest areas is more than 10 years, meaning that low-income workers effectively subsidise the retirement of the wealthy.
Trade unions have warned that privatisation or means-testing of the state pension would be a disaster for low earners. “It would turn what should be a universal right into a handout for the poorest, creating a two-tier retirement system,” said Mary Thompson of the Trades Union Congress. “We need to look at higher taxes on wealth and corporate profits to shore up the system, not cut it to the bone.”
The generation that grew up with austerity, economic shocks, and the gig economy is now facing the prospect of working decades longer than their parents. For many, the future is already being shaped by a quiet resignation. “I’m just hoping I can pay off my student loan before I die,” a Gen Z worker joked bitterly on social media. But it is no joke – it is the defining economic challenge of our time.
Experts say the government must act now. Reforms could include raising contribution levels, lowering the pension age for those in physically demanding jobs, or changing the triple lock. But each option carries political pain. In the meantime, young people are doing what they have always done: adapting. Yet adaptation has limits when the cost of living leaves little room for savings. The Treasury briefing ends with a warning: “If we fail to act, a generation will face a retirement of poverty, and the consequences will ripple through the entire economy.”
