The Americans who never finished high school held $2.3 trillion in household wealth at the end of 2025. In 1989, that same group had $2.4 trillion. Thirty-six years. Three and a half decades during which the US economy grew enormously, the stock market went up roughly 25 times, and total household wealth expanded from $21 trillion to $175 trillion. The bottom rung of the education ladder ended up essentially where it started — except that everything around it got vastly more expensive.
The numbers come from the Federal Reserve's Distributional Financial Accounts — a quarterly dataset tracking household balance sheets by education group since 1989. The DFA uses the Fed's full Flow of Funds data, cross-checked against the Survey of Consumer Finances, covering every household in the country. It does not rely on self-reporting. It does not miss the rich. It just measures.
What it measures, in 1989, is college graduates controlling 50 percent of all US household wealth. By end of 2025 that share was 75.6 percent. Their aggregate wealth grew from $10.4 trillion to $132.5 trillion — a 12.8-fold increase in nominal terms. Over the same period, total US household wealth grew 8.4 times. College graduates did not just keep their share of a growing pie. They took more of it.
It’s Not the Paycheck
The wage premium attached to a college degree is real. Lifetime earnings for a bachelor's degree holder run roughly $1 million more than for a high school diploma holder, before taxes and before the cost of the degree itself. That gap produces more savings, which compound, which build wealth. The arithmetic works. But it does not explain a 12.8-fold increase versus essentially zero.
Run the numbers. A $50,000 annual income advantage, invested at a plausible savings rate, compounded over 36 years, does not produce an outcome where one group's wealth grows 12 times and another's stagnates in nominal terms for three and a half decades. Something else is doing most of the work.
That something is the stock market.
The DFA breaks down what each education group actually owns. In 1989, college graduates kept 12 percent of their total gross assets in corporate equities and mutual funds. By 2025, that figure had risen to 34 percent. The no-diploma group started at 3.4 percent and reached 8.6 percent. Both groups more than doubled their relative equity exposure. But college graduates did it from a far higher base, during a period in which US equities grew roughly 25 times. Real estate, by comparison, roughly doubled in real terms. If you owned stocks, you got rich. If you owned a house, you kept up with inflation. If you owned mostly a house in a neighborhood that did not appreciate, you fell behind everyone else.
Look at the real estate figures and the picture gets sharper. College graduates held 26 percent of their assets in real estate in 1989. By 2025 that share had declined to 22 percent — they diversified into equities as their portfolios grew. The no-diploma group went the other direction: from 34 percent real estate to 48 percent. Nearly half of everything they own now sits in residential property. An asset that requires financing to acquire, produces no dividends, concentrates all your risk in one address and turns illiquid at exactly the worst time — during a downturn, when you might actually need the cash.
The 2008 financial crisis made the difference visible in the data. At the trough of the housing market in 2010, the no-diploma group's aggregate net worth had fallen to $1.6 trillion — a 31 percent drop from its 2007 level. College graduates fell 12 percent from their peak and recovered within three years. High school diploma holders, similarly concentrated in home equity, fell 15 percent and took longer to come back. The groups that owned stocks watched those stocks crash. Then watched them recover. The groups that owned mostly houses spent a decade waiting for a market that kept running without them.
In 2015, as housing finally recovered, the no-diploma group briefly surpassed its 1989 wealth level for the first time in 26 years. Then the stock market resumed climbing. By 2025 they were back below 1989 again. In real dollars, they had lost more than half.
Why This Keeps Happening
The connection between a college degree and equity ownership is not accidental. Several forces reinforce it simultaneously, and they all push in the same direction.
The most direct is the 401(k) match. Employer matching on retirement contributions is, in financial terms, a 50-to-100 percent instant return on every dollar saved. That offer is concentrated at the top of the labor market — professional services, technology, finance, healthcare administration. A software engineer at a Fortune 500 company may receive full matching from the first month of employment, in the form of diversified equity funds. A warehouse worker at the same firm often receives nothing. Both work at the same company. One is being handed equity. The other is not.
Then there is the cultural channel. Professional environments treat investing as ordinary. Colleagues discuss index funds and brokerage accounts. Financial advisors call because the math says to. The vocabulary of compound returns moves from the financial press into office small talk. None of this produces a specific return on any individual dollar. But it reliably raises the probability that surplus income — when it exists — ends up in the market rather than a savings account.
Third is timing. College graduates entered the labor force with higher early incomes, which meant more to invest at an earlier age. Given that the S&P 500 returned roughly 10.7 percent annually from 1989 to 2025, a single decade of earlier investing compounds into an enormous difference in terminal wealth. The degree did not produce those market returns. It got its holder into the market in time to benefit from them.
The defined-contribution data makes this concrete. In 1989, college graduates held $600 billion in 401(k)-style accounts. By 2025 that had grown to $12 trillion — a 20-fold increase. High school diploma holders went from $186 billion to $1.3 trillion: a 7-fold increase. That gap is not explained by salary alone. It is a story of who had an employer offering a plan, who was matched, and who had enough financial slack to contribute at all.
The Wrong Question
The data does not settle the college-debt argument. Average student debt at graduation for those who borrow runs roughly $37,000. At current interest rates that costs real money across a decade. And these are aggregate figures — they average across graduates from wealthy families who finished debt-free and walked straight into high-paying careers. The distribution within the college-educated group is itself sharply unequal. Some of the gains at the top are extreme enough to pull the whole average upward.
The skilled-trades argument — that electricians and plumbers earn real wages and do not need a four-year degree — is correct on income. The high school diploma category in the DFA includes many skilled tradespeople. That group's wealth grew from $4.2 trillion to $15.7 trillion, a 3.7-fold nominal increase over 36 years. Adjust for inflation and the real gain is about 47 percent. A genuine improvement. College graduates, in real terms, more than quadrupled. The difference is not wages. It is what each group ended up owning.
One honest caveat: these figures measure aggregate wealth, not per-capita wealth. The no-diploma group has shrunk significantly as high school graduation rates improved. Some of the stagnation in aggregate wealth reflects fewer people in the category, not just declining wealth per person. Per capita, the decline is somewhat less severe. But aggregate figures tell you the total economic weight of a demographic cohort. The no-diploma group's total economic weight, measured this way, has not moved in 36 years.
The 36-year divergence in the DFA is not complicated, once you accept what it is actually measuring. It is not primarily a story about credentials or career ladders. It is a story about who was in the stock market when it went up 25 times. College graduates were in it — because they earned enough to contribute, because their employers matched those contributions, and because the professional culture they entered treated equity ownership as routine. That is what a degree bought, beyond the wage premium. Whether it was worth the cost of getting one is a personal calculation that depends on debt load, field and a fair amount of luck. The Federal Reserve's data just shows what happened to the money.
