The American Century’s Wealth Pyramid Is Dead—And Its Replacement Is Spinning Out of Control

For 80 years, Henry Luce’s 1941 “American Century” essay anchored a global economic consensus. The U.S. sat atop a wealth pyramid. Its middle class was the global standard for stable, abundant life. Even the poorest American households ranked near the 70th percentile of global income in 2009, per Columbia and Federal Reserve Bank of New York economists. That pyramid no longer holds.

The new global wealth shape starts with a shrinking base. World Data Lab reported in 2025 that the global consumer class now dominates worldwide for the first time. Brookings projects 5.3 billion global middle class members by 2030. Two-thirds of that group will live in Asia. The UBS 2026 Global Wealth Report adds hard numbers. Global personal wealth rose 10.8% in 2025. That’s the fastest pace since 2017, more than twice 2023 and 2024’s rates. Nearly 1 million new millionaires were created. The share of adults with less than $10,000 in wealth fell from 75% in 2000 to just over 41% today. But median wealth dropped in most of the 56 tracked markets, even as averages surged. The U.S. exemplifies this gap. It ranks second globally for average wealth per adult at $696,277. It ranks 28th for median wealth at $68,998. Its Gini coefficient is 0.77, the sixth worst worldwide.

The apex of this new shape isn’t a stable point—it’s a spinning top. The $5 million to $100 million “everyday millionaire” cohort grew double-digit in 2025. Its real annual wealth growth hit 8.7% since 2000, more than double regular millionaires. China’s $50 million to $100 million group saw 31% annual growth. The World Inequality Report 2026 found 56,000 ultra-wealthy individuals control more wealth than the poorest 4 billion people. Their share of global wealth has doubled since 1995. This capital rotates faster than regulation or taxation can track. It shifts between asset classes and jurisdictions constantly. UBS chief economist Paul Donovan notes the upper-middle class, with index funds and 401(k)s, has more in common with this spinning apex than the lower wealth base. Governments will likely try to mobilize wealth to lower debt financing costs. But equity market gains will only widen inequality further. The system’s stability depends on a middle class invested in protecting its assets. Rising home prices have locked younger workers out of homeownership, fraying that bond.
