There are certain facts that, once you hear them, you can’t really unhear. I came across one recently that stopped me cold. A 40-year-old man living in poverty in the United States has a life expectancy roughly the same as a man living in Pakistan or Sudan. Not similar. Roughly the same.

Now sit with that for a moment. We’re talking about the wealthiest country in the history of human civilization. A nation that spends more on healthcare per person than any other country on Earth. And yet somewhere between those impressive numbers and the actual lives of the poorest Americans, something has broken down in a very serious way.

I want to walk you through this today not just the moral outrage of it, which is obvious, but the economic machinery underneath it. Because once you understand how wealth and lifespan feed each other, you start to see why this problem doesn’t just persist. It accelerates.

The Obvious Answer And Why It’s Only Half the Story

Let’s start with the part everyone already knows. Wealthy people live longer because they eat better, live in safer neighbourhoods, work jobs that don’t destroy their bodies over 20 or 30 years, and can actually afford to see a doctor before a small problem becomes a terminal one.

In the UK, the poorest fifth of the population would need to spend 50% of their disposable income just to hit the government’s basic recommended healthy diet. So when we talk about poor nutrition in low-income households, we need to stop framing it as a lifestyle choice and start calling it what it actually is a financial constraint.

On top of that, tobacco use runs at nearly three times the rate in low-income households compared to wealthy ones.

And wealthy people, when life gets difficult, generally have better options available to them than the coping mechanisms that tend to shorten a life.

Here’s something that surprised me: wealth even overrides the biological advantages you were born with. Women live longer than men almost everywhere on Earth. But at the very bottom of the income scale in America, women live around 6 years longer than men. At the very top, that gap shrinks to about one and a half years. Because a huge portion of what kills men early dangerous work, chronic stress, harmful coping habits are things money can directly address or remove.

Where you live matters enormously too. Property near industrial plants and busy roads is cheaper, which is why lower-income families end up there, breathing measurably worse air, and facing higher rates of respiratory and cardiovascular disease.

When you map life expectancy across England by area, the gap between someone in wealthy Kensington and someone in Blackpool is roughly 10 years.

And if you look at healthy life expectancy years lived in good health, not just years lived a woman in Richmond upon Thames is expected to enjoy nearly 20 more healthy years than a woman in Hartlepool. Twenty years. In the same country. With the same national health system.

The Status Syndrome A Study That Changed Everything

Now here’s where it gets genuinely fascinating, because all the factors above food, housing, pollution, healthcare access still don’t fully explain the gap. If they did, two government workers with identical salaries, job security, and access to the same national health system should die at roughly the same age.

They don’t.

In the late 1960s, a British epidemiologist named Michael Marmot began tracking around 18,000 civil servants working in Whitehall the heart of the British government.

These were not people in poverty. Stable employment, regular salaries, access to the NHS. Same employer, same city. And yet Marmot found that people at the bottom of the office hierarchy were dying at three times the rate of those at the top.

He called it the Status Syndrome. And when he dug into the cause, he kept coming back to one thing: control.

A senior civil servant could take a long lunch, restructure their afternoon, make decisions about their own time. Someone at the bottom had none of that. Their day was managed, monitored, dictated. And that chronic, unrelenting experience of having no agency over your own life turns out to be quietly devastating to the human body.

We tend to picture stress as something dramatic a CEO sweating through a billion-dollar decision. But that kind of acute stress lifts when the decision is made. The stress Marmot identified doesn’t go away. It just sits there, raising blood pressure, weakening the immune system, and quietly increasing the risk of heart disease and stroke over years. You might not even call it stress. It just becomes the texture of daily life.

The conclusion, stripped of all the academic language, is fairly simple: the more control you have over your working life, the longer that life tends to be.

The Compounding Advantage of Living Longer

This is the part of the story that I think most people miss entirely, and honestly, it’s the part that keeps me up at night.

Extra years of life aren’t just extra years of enjoyment. For people who already have wealth, they are extra years of compounding. Warren Buffett made 99% of his wealth after the age of 50. His real edge wasn’t just skill. It was time.

At a standard long-run market return of around 7% per year, money roughly doubles every decade. So for someone with significant assets say $5 million those extra 14 years of life translate to close to $13 million in additional growth.

Meanwhile, the financial benefits of living longer are distributed wildly unevenly. Wealthy households own appreciating assets stocks, businessesthat compound across decades. Most middle-income retirees don’t. Their financial security is tied up in home equity and pension entitlements. And here’s the brutal comparison: since 1995, US home prices are up around 310%.

The S&P 500 is up over 2,300% in the same period. A hundred dollars put into housing in 1970 would be worth around $1,600 today. The same hundred dollars in the S&P 500? $33,420.

For people without an investment portfolio, every extra year of life after retirement is another year of depletion, not accumulation. Someone retiring today will spend around 5 years longer in retirement than their grandparents did. That’s nearly a third more retirement to fund. And yet most people still build their retirement plan based on how long they watched the generation before them live.

That’s why 64% of Americans say they are more afraid of running out of money in retirement than they are of dying.

Inheritance The Head Start You Either Got or Didn’t

A lot of people pin their hopes on inheritance. But even this plays out very differently depending on which family you were born into.

For wealthy families, inheritance is almost beside the point because wealthy parents don’t wait until they die to transfer money. In the UK, more than half the total value of financial gifts to adult children comes from the wealthiest fifth of families. The wealthy child has already received the house deposit, the school fees, the interest-free business loan.

By the time the formal inheritance arrives, they’re already financially established. The money goes straight into investments. It compounds. The family gets wealthier still.

For middle-income families, the median age of receiving an inheritance is around 61. By then, they’ve already bought the home, built the career, and navigated the hard decades alone.

The inheritance helps maybe it pays down the mortgage or tops up the pension but it doesn’t change the trajectory. And the median inheritance in the UK is £11,000, which wouldn’t cover a deposit on a home in most of the country.

For lower-income families, the inheritance often arrives earlier because parents die younger. That sounds like an advantage. But it means the money gets used, not invested. Lower-income heirs typically deplete whatever they receive within a decade. And if the parent defies the odds and lives longer, the inheritance arrives after the key wealth-building years are already over.

The Pension System’s Dirty Secret

Here is something that rarely gets said plainly: pension systems, as currently designed, flow disproportionately toward people who need them least.

These systems were built on the assumption that people live roughly similar lengths of time after retiring. But when wealthier workers consistently live more than a decade longer than poorer ones, they collect pension benefits for far more years. In Germany and the United States, the lifespan gap is large enough to cancel out all the redistribution the pension system was actually designed to create.

Meanwhile, lower-income workers who do survive into old age didn’t contribute as much to their own savings, and now those savings have to stretch across more years than anyone planned for. The projection forward is stark: poverty rates among retirees could double when millennials retire.

What Are We Actually Doing About It?

There are two main solutions being seriously discussed right now, and they could not be more different in both approach and ambition.

The first is baby bonds. The idea is that every child born gets a government-funded investment account $1,000 at birth, growing at a fixed rate, with additional annual top-ups for lower-income families. By age 18, that account could reach around $46,000 for children from poorer households.

Projections suggest a properly structured national baby bonds programme could reduce the wealth gap from 14 times between the richest and poorest families to roughly five times. And because wealth buys time, it could extend average lifespan by up to 6 years for people currently at the very bottom. Connecticut has already launched a version of this at state level. It’s promising but we won’t see real results until the 2040s.

The second “solution” is simply raising the retirement age. France tried it in 2023, pushing from 62 to 64. The government had to bypass parliament entirely to pass it. A million people took to the streets. By late 2025, the National Assembly had voted to suspend it entirely.

And honestly? The protesters had a point. Raising the retirement age only makes sense if everyone ages the same way.

A senior manager at 64 still has their health, their cognitive function, and work that doesn’t physically break them. A construction worker or a nurse at 64 does not have that luxury.

Raising the age for everyone equally hits the people in physically demanding, lower-income jobs the hardest the exact people who are already living shorter lives. The smarter version ties retirement eligibility to job type, which France itself already does partially through its long careers scheme, allowing people who entered the workforce at 16 or 18 to retire years earlier.

Wrapping It All Up

Here’s what I keep coming back to: this isn’t a problem about individual choices or bad luck. It’s a system that compounds. Poverty leads to worse health. Worse health leads to a shorter life.

A shorter life means less time to build wealth and less wealth to pass on. And round it goes, getting a little worse with each generation.

The gap in median lifespan between the wealthiest and poorest Americans is projected to grow from around 8 years for people currently in their 80s to roughly 15 years for people now in their early 60s.

The wealthiest Americans are on track to live 8 additional years compared to their parents. For the poorest, the gain is practically zero. The next generation of poorer women is expected to die younger than their mothers.

None of this is inevitable. But fixing it requires acknowledging what it actually is not a health problem, not a lifestyle problem, but a structural economic problem that needs structural economic solutions. Baby bonds are a genuine long-term tool. Smarter pension reform that accounts for physical labour and lifespan differences is another. But doing nothing while describing the problem in increasingly sophisticated terms is not a solution.

That’s a tradition we really should break.
