The Middle Class Is Shrinking Because More Americans Are Becoming Millionaires

America continues to produce more new millionaires than any other country in the world, offering fresh evidence that economic growth and opportunity remain widely available. While critics often argue that the middle class is disappearing because Americans are falling behind, long-term income data suggest a different trend. A growing share of households have moved into higher income brackets, reflecting rising prosperity rather than widespread economic decline.

According to the UBS Global Wealth Report 2026, the United States added approximately 440,000 new millionaires in 2025, or about 1,200 every day. Americans accounted for nearly half of all new millionaires worldwide, reinforcing the country's position as the world's leading engine of wealth creation.

Long-Term Income Trends Show Upward Mobility

Claims that the American middle class is being hollowed out often overlook how household incomes have changed over time.

Census Bureau data adjusted for inflation show that the share of U.S. households earning at least $100,000 annually in 2022 dollars increased from 13.1 percent in 1967 to 37.5 percent in 2022. Over the same period, the share of low-income households earning $35,000 or less declined from 32.3 percent to 23.3 percent.

The middle-income share has become smaller over time, but that does not necessarily indicate declining living standards. As household incomes rise, many families naturally move into higher income categories. Much of the long-term change reflects upward mobility rather than movement into lower-income status.

America Continues to Create Wealth

The United States is home to 23.6 million millionaires, according to UBS. Mainland China ranks a distant second with 5.3 million, followed by Japan with 2.9 million and Germany with 2.6 million.

The addition of approximately 440,000 new millionaires in a single year reflects an economy that continues to reward entrepreneurship, investment, innovation, and long-term savings. Many Americans accumulate wealth gradually through business ownership, retirement accounts, homeownership, and decades of disciplined investing rather than sudden financial gains.

As more households build wealth, they move beyond the middle-income category. That upward movement helps explain why the middle class represents a smaller share of the population today than it did several decades ago. In many cases, the change reflects economic success rather than economic decline.

Policies That Reward Growth Expand Opportunity

Economic mobility depends on policies that encourage investment, innovation, business formation, and capital accumulation. When individuals and businesses have stronger incentives to work, save, invest, and take entrepreneurial risks, the economy expands and more households have opportunities to increase both income and wealth.

By contrast, policies that discourage investment or reduce incentives for economic growth make it more difficult for families to build wealth over time.

America's continued leadership in wealth creation reflects the long-term benefits of an economy that rewards productive activity and expands opportunities for upward mobility.

CFE Takeaway

The narrative that the American middle class is disappearing because families are being pushed backward is difficult to reconcile with the long-term data. Census Bureau statistics show that the share of high-income households has grown substantially while the share of low-income households has declined. The UBS Global Wealth Report provides another measure of that progress, finding that the United States created roughly 1,200 new millionaires every day in 2025. A smaller middle class is not necessarily evidence of economic decline. In many cases, it reflects more Americans moving into higher income and wealth brackets, demonstrating that the American Dream remains within reach for millions of families.
