McKinsey Global Institute reports that $600 trillion of wealth rests on productivity or price highlights that much of the rise in value has been driven by asset prices often outpacing underlying economic growth, leaving asset value gains (real estate, equities) that disproportionately accrue to the wealthy, according to McKinsey Global Institute.
This unprecedented accumulation reveals an uncomfortable truth: Much of today’s wealth isn’t built on economic productivity but on inflated asset prices that primarily benefit those who already own significant assets.
GOBankingRates breaks down how massive asset bubble is keeping the rich richer and what it means for everyday Americans.
Paper Wealth Disconnected From Reality
Entering 2025, the world’s wealth reached $600 trillion, its highest amount ever. Yet much of its growth came from asset price increases, funded by a proliferation of debt, rather than new saving and investment.
The research reveals a troubling pattern: More than a third of the $400 trillion rise in wealth since the turn of the century was essentially just paper gains, decoupled from the real economy, and about 40% was cumulative inflation. This means only 30% reflected new investment in the real economy.
Put another way, every $1 in investment generated $2 in debt.

The Wealth Concentration Problem
While global wealth reaches record highs, its distribution remains starkly unequal. The top 1% of people hold at least 20% of wealth. According to Eulerpool’s analysis of the McKinsey data, wealth continues to concentrate: The top 1% holds 35% of U.S. wealth (averaging $16.5 million), in Germany 28% (averaging $9.1 million).
This concentration occurs because asset ownership itself drives wealth accumulation. Those who own stocks, real estate and other appreciating assets see their wealth multiply through price increases disconnected from underlying economic productivity, while those without significant asset holdings fall further behind regardless of their income or savings habits.
The Everything Bubble Phenomenon
Financial markets are experiencing what economists call an “everything bubble.” The “everything bubble” refers to the impact on the values of asset prices, including equities, real estate, bonds, many commodities, and cryptocurrencies, due to quantitative easing by the Federal Reserve, European Central Bank, and the Bank of Japan, according to financial historians.
Current asset prices, including U.S. stocks and real estate, are at extreme valuations due to years of easy monetary policy and money supply growth, warns a Seeking Alpha analysis. The Federal Reserve’s actions, especially during and after COVID-19, fueled inflation and asset bubbles simultaneously.
Four Possible Scenarios
McKinsey outlines four potential futures for this unprecedented wealth accumulation. The best outcome requires a productivity boom, perhaps sown by the quantum leap in AI now unfolding, that allows growth to catch up, stock values to stay strong without overheating wages and prices.
However, “Economies are unlikely to achieve balance while preserving wealth and growth unless productivity accelerates,” MGI said. “Other scenarios sacrifice one or the other or both.”
For the average U.S. saver, the difference between the two most likely scenarios could amount to as much $160,000 by 2033.
What This Means for Average Americans
The disconnect between asset wealth and economic reality creates a two-tiered economy. Those with substantial investments in stocks, real estate or other assets see their wealth compound through price appreciation. Meanwhile, wage earners without significant asset holdings struggle to accumulate wealth despite working productively.
This dynamic explains why wealth inequality continues widening even during periods of economic growth and low unemployment. Asset price inflation benefits asset owners disproportionately, creating what economists call a “K-shaped recovery” where the wealthy thrive while others fall behind.
The Bottom Line
The world’s $600 trillion in wealth increasingly rests on asset price inflation rather than productive economic growth, creating unprecedented wealth concentration among the top 1%.
With more than a third of wealth gains since 2000 representing paper gains disconnected from real economic activity, and every dollar of investment generating two dollars in debt, the current system disproportionately enriches those who already own appreciating assets.
Unless productivity accelerates dramatically, this asset bubble threatens either prolonged inflation that erodes purchasing power or a painful reset that could wipe out trillions in paper wealth.
