Driven largely by the accumulation of massive wealth by the richest people in the United States, the Swiss wealth manager UBS said Thursday the assets of billionaires around the world more than doubled over the past decade.

Between 2015-24, the total wealth of billionaires increased by 121%, from $6.3 trillion to $14 trillion.

Meanwhile, the MSCI AC World Index of global equities, which measures the performance of more than 3,000 stocks from both developed and emerging markets, rose by 73%.

The planet’s total gross domestic product is about $105.4 trillion, with a population of just over 8 billion, underscoring the extreme concentration of wealth among the very richest people.

The number of billionaires rose from 1,757 to 2,682 over the past decade, while the wealthiest people in the world boasted significant gains over just the past year.

Billionaires’ wealth jumped by about 17% in 2024, with the accumulation of wealth among the richest people in the U.S. offsetting a decline in China.

U.S. billionaires amassed wealth gains that were 27.6% higher than the previous year, accumulating a total of $5.8 trillion — more than 40% of international billionaire wealth.

The tax cuts pushed through by President-elect Donald Trump and the Republican Party in 2017 are still in effect in the U.S. Tax policy analysts have found that the law was skewed to the rich, with households in the top 1% of incomes expecting to receive an average tax cut of more than $60,000 in 2025 compared to an average tax cut of less than $500 for people in the bottom 60%.

As Common Dreams reported this week, the top 12 U.S. billionaires now control $2 trillion. The wealth of the four richest people in the U.S. — Tesla CEO Elon Musk, Amazon founder Jeff Bezos, Oracle co-founder Larry Ellison, and Meta CEO Mark Zuckerberg — has hit $1 trillion.

“These four men were worth $74 billion 12 short years ago,” said Americans for Tax Fairness. “Tax billionaires.”

At the G20 Summit last month, world leaders agreed to “engage cooperatively to ensure that ultra-high-net-worth individuals are effectively taxed.”

A terrifying moment. We appeal for your support.

In the last weeks, we have witnessed an authoritarian assault on communities in Minnesota and across the nation.

The need for truthful, grassroots reporting is urgent at this cataclysmic historical moment. Yet, Trump-aligned billionaires and other allies have taken over many legacy media outlets — the culmination of a decades-long campaign to place control of the narrative into the hands of the political right.
