For decades, economic gains in the United States have been distributed unevenly, with affluent households capturing an increasingly large share of the nation’s wealth.
Data from the Federal Reserve show that households in the highest-earning 10% controlled 32% of total US wealth in 1989. By 2025, their share had risen to 68%, according to analysis from CNN.
Economists often describe this pattern as a K-shaped economy, where wealthier households continue to advance while those lower down the income ladder struggle to keep pace. The divergence has become even more pronounced in recent years, particularly since the inflation surge that began about three years ago.
The growing gap is influenced not only by income levels but also by differences in asset ownership and spending patterns.
Although households across all income groups have seen their wealth increase over the past three years, the gains have been far from equal. The wealthiest 1% recorded a 30% increase in net worth during the period, while the middle 40% experienced growth of less than 10%.
Three factors largely explain the disparity: property ownership, stock market exposure and inflation.
A substantial portion of the country’s housing wealth is concentrated among higher-income households. The top 20% own more than half of the total value of US residential property, benefiting from strong increases in home prices in recent years. Meanwhile, rising mortgage rates have made homeownership increasingly difficult for lower-income Americans, with the bottom 20% holding only 3% of the nation’s housing value.
The divide was further reinforced in the years following the pandemic. As mortgage rates fell to record lows, homeowners refinanced their loans and accessed around $430 billion in home equity, providing them with an additional financial advantage.
The concentration of financial assets is similarly skewed. More than three-quarters of US financial holdings, including shares, belong to the top 20% of households, while the top 1% alone owns more than one-quarter. Over the past three years, the S&P 500 index has risen by 86.2%, generating significant gains for investors. By comparison, cash savings have delivered average returns of less than 1% annually over the same period.
Price increases have not affected all households equally. Lower-income families typically devote a larger share of their budgets to essentials such as housing and food, categories that have experienced stronger price growth than many of the goods and services purchased by wealthier households.
According to the Minneapolis Federal Reserve, consumer prices between 2005 and 2023 increased by 57% for the lowest-income 20% of Americans, compared with 46% for the highest-income 20%.
Consumer spending trends also highlight the economic divide. Households earning less than $40,000 annually began cutting back their spending in January 2023 and did not stabilise until September 2024.
Over the past three years, inflation-adjusted spending among this group increased by only 1.3%. In contrast, households with annual incomes of at least $125,000 expanded their real spending by 7.6%.
Robust spending by higher-income households has also supported demand across the economy, contributing to persistent price pressures that affect consumers more broadly.
As a result, wealthier Americans benefit not only from larger incomes but also from greater access to assets that appreciate in value, particularly housing and equities. At the same time, they are generally better positioned to absorb the effects of inflation, giving them a stronger platform for further wealth accumulation than lower-income households.
