Millennials are set to inherit close to $124 trillion from their Baby Boomer parents and grandparents over the next two decades — a transfer so massive it has been dubbed the Great Wealth Transfer. If those projections hold, millennials will become the wealthiest generation in recorded history, not because of what they earned, but because of what they stand to receive. Asset management giant Vanguard expects more than $18 trillion alone to change hands globally by 2030. But before younger generations start planning how to spend it, history has a sharp warning: inherited wealth has a habit of vanishing faster than it was built.
What Is the Great Wealth Transfer?
The Great Wealth Transfer refers to the historic movement of assets — primarily real estate, stocks, and private businesses — from the Baby Boomer generation to their Millennial and Gen X children and grandchildren. Baby Boomers, born between 1946 and 1964, benefited from decades of extraordinary economic expansion, soaring property values, and equity market growth that compounded over their lifetimes.

According to research by The Economist, inheritance as a share of national income in developed economies has roughly doubled since the mid-20th century. In 2024 alone, people across the wealthy world are expected to inherit approximately $6 trillion. That figure was closer to 5% of US GDP in the late 1970s; by the end of the 2000s it had rebounded to around 10% of GDP on average across developed nations.
Baby Boomers currently own an outsized share of national assets. In the United States, they hold 37% of all housing stock while representing only about 20% of the population. They own 57% of vacation homes, 58% of rental properties, and 41% of small businesses — worth a combined $8 trillion. Much of this will be passed on in the coming decades.
How Much Will Millennials Actually Inherit?
The headline number — $124 trillion — sounds extraordinary, but the distribution is deeply uneven. Federal Reserve data shows that the top 1% of inheritors in the United States will capture approximately 50% of all wealth transfers. Meanwhile, around 60% of Americans will inherit less than $5,000. The average inheritance in the US has quadrupled since 1995, rising from roughly $100,000 to nearly $400,000 today — but that average is heavily skewed by enormous transfers at the top.

Falling birth rates are quietly inflating individual inheritance amounts. Fewer children means less splitting of estates, and The Economist estimates that declining birth rates have already raised the amount going to the average inheritor by around $75,000 — a 24% increase compared to what inheritances looked like when estates were divided among larger families.
In the United Kingdom, one in six people born in the 1960s can expect an inheritance worth more than ten years of average annual income. For those born in the 1980s, that ratio rises to one in three — a dramatic generational shift that reflects both the aging of Boomers and the explosion in UK property values.
Why Do Most Inherited Fortunes Disappear?
History is littered with examples of vast fortunes that evaporated within a generation or two. The most famous is Cornelius Vanderbilt, who died in 1877 leaving his eldest son the largest fortune in the world at the time — over $100 million. Within just 70 years, the entire Vanderbilt fortune was gone. Reckless spending and poor investment decisions by heirs eliminated wealth that, had it simply been invested in a broad market index, would have grown into one of the largest fortunes on Earth.
This is not unusual. A 20-year study by the Williams Group, covering 3,200 families, found that 70% of wealthy families lose their fortune by the second generation, and 90% by the third. The causes vary — family disputes, legal battles, failed investments, and lifestyle inflation all play a role. As the book The Missing Billionaires by Haghani and White explores, the mathematics of wealth destruction through spending and poor allocation is relentless.

Booth Tarkington's novel The Magnificent Ambersons captured this dynamic brilliantly: a wealthy Midwestern family's fortune collapses over three generations as heirs fail to adapt to economic change, spending lavishly while the industrious families around them build new wealth from scratch. The lesson is timeless — inherited capital managed passively by uninterested or undisciplined heirs tends to shrink.
Why Slow Economies Become Inheritance Economies
One of the most striking findings from The Economist's research is that inheritance grows fastest — relative to national income — in slow-growing economies. Italy is the clearest example: when Italy's economy stalled in the mid-1990s, inheritance flows as a share of national income shot up from around 7% in 1990 to roughly 19% by 2023. Today, 60% of Italian billionaires inherited their wealth.
The mechanism is straightforward. When economic growth slows, wages stagnate and business profitability declines. The older generation — who accumulated savings during more prosperous times — holds proportionally more wealth than the current economy can generate. Simultaneously, central banks respond to slow growth by cutting interest rates, which inflates asset prices like real estate and equities. Those who already own assets see their wealth grow faster than those relying on earned income.
By contrast, faster-growing economies like the United States and Ireland have seen inheritance grow more slowly relative to national income. In the US, research by Kaplan and Rauh shows that the share of Forbes 400 members who inherited family wealth has actually declined since the 1980s, replaced by self-made entrepreneurs like Bill Gates, Warren Buffett, Philip Knight, and Stephen Schwarzman — people who grew up in the upper-middle class and built their companies from scratch.

How Much Has the Average US Inheritance Grown?
The numbers are stark. In 1995, the average inheritance received by Americans was approximately $100,000. Today that figure is approaching $400,000 — a fourfold increase in less than 30 years. The primary driver is housing. Baby Boomers who purchased homes in cities like New York, San Francisco, and London decades ago at modest prices are now sitting on properties worth millions.
In Britain, the total value of housing owned by residents has jumped from just over £1 trillion — roughly 130% of GDP in the mid-1990s — to nearly £7 trillion today, representing 270% of British GDP. Restrictive planning policies have constrained housing supply, pushing prices far beyond wage growth and making the family home one of the most valuable assets an ordinary person can pass on.
Many Baby Boomers are not waiting until death to transfer wealth. Bank of Mum and Dad is now so significant that, according to research by Legal & General, if it were an actual bank it would rank among the top ten mortgage lenders in the United States. Parents and grandparents are funding down payments, private school fees, and student loan repayments in real time — transferring wealth across generations while still alive.
Does Inheritance Make Inequality Worse?
The concentration of inheritance flows is difficult to ignore. With the top 1% capturing half of all wealth transfers and the majority of Americans receiving almost nothing, critics argue that inheritance systematically entrenches inequality. When capital moves from risk-taking founders to passive heirs, it can also reduce the economic dynamism that drives innovation and job creation.
There is also a more subtle concern: as inherited wealth grows more important than earned income in certain economies, the link between individual merit and financial outcome weakens. Ambitious young people in stagnant economies may rationally shift their focus from building businesses to securing advantageous marriages — a trend The Financial Times reports has increased sharply since the pandemic.
Why Do People Hate Inheritance Taxes So Much?
Despite the inequality concerns, inheritance taxes remain among the most unpopular forms of taxation almost everywhere. Surveys consistently show that people object on multiple grounds: they believe parents should be free to support their children with after-tax savings; they view estate taxes as double taxation on income already taxed once; they worry that high inheritance taxes push wealthy families to emigrate; and they fear such taxes discourage saving in favor of consumption.
Perhaps most strikingly, opposition to inheritance taxes is actually stronger among lower-income households than among the wealthy — a pattern economists have long found puzzling. Milton Friedman addressed this in his television series Free to Choose, noting the remarkable fact that parents who know their children will likely be richer than them still prioritize saving money to leave behind — suggesting people place genuine value on their children's future consumption, not just their own.
Are Millennials Counting on Inheritance? The Data Is Alarming
Research by Charles Schwab reveals a potentially dangerous gap between expectation and reality. According to their surveys, 53% of young people expect to receive an inheritance from their parents — yet only 21% of people actually receive one. Young people also expect to retire earlier than their parents did, while saving less toward retirement than their parents saved at the same age. Only 40% of young respondents could pass a basic financial literacy test.
The concern is that a generation partly counting on inherited wealth to fund their retirement is also the generation least prepared to manage a large lump sum when it arrives. History — from the Vanderbilts to the Ambersons — suggests that financial literacy and disciplined investment habits matter far more than the size of the inheritance itself. As The Economist's data shows, wealth that takes a lifetime to build can disappear within a generation when passed to unprepared hands.
The Great Wealth Transfer is real, it is enormous, and it is already underway. Whether it creates lasting prosperity for the next generation — or simply funds a very expensive few decades of consumption — will depend less on the size of the transfer and more on what recipients choose to do with it.
