In 2024, wealth concentration rose to an all-time high. According to Forbes’ Billionaires List, not only are there more billionaires than ever—2,781—but those billionaires are also richer than ever, with an aggregate worth of $14.2 trillion. This is a trend that looks set to continue unabated. A recent report from the financial data company Altrata estimated that about 1.2 million individuals who are worth more than $5 million will pass on a collective wealth of almost $31 trillion over the next decade.
Discontentment and concern over the consequences of extreme wealth in our society is growing. Senator Bernie Sanders, for instance, stated that the “obscene level of income and wealth inequality in America is a profoundly moral issue.” In a joint op-ed for CNN in 2023, Democratic congresswoman Barbara Lee and Disney heiress Abigail Disney wrote that “extreme wealth inequality is a threat to our economy and democracy.” In 2024, when the board of Tesla put to vote a $56 billion pay package for Elon Musk, some major shareholders voted against it, declaring that such a compensation level was “absurd” and “ridiculous.”
In 2025, the fight against rising wealth inequality will be high on the political agenda. In July 2024, the G20—the world’s 20 biggest economies—agreed to work on a proposal by Brazil to introduce a new global “billionaire tax” that would levy a 2 percent tax on assets worth more than $1 billion. This would raise an estimated $250 billion a year. While this specific proposal was not endorsed in the Rio declaration, the G20 countries agreed that the super rich should be taxed more.
Progressive politicians won’t be the only ones trying to address this problem. In 2025, millionaires themselves will increasingly mobilize and put pressure on political leaders. One such movement is Patriotic Millionaires, a nonpartisan group of multimillionaires who are already publicly campaigning and privately lobbying the American Congress for a guaranteed living wage for all, a fair tax system, and the protection of equal representation. “Millionaires and large corporations—who have benefited most from our country’s assets—should pay a larger percentage of the tab for running the country,” reads their value statement. Members include Abigail Disney, former BlackRock executive Morris Pearl, legal scholar Lawrence Lessig, screenwriter Norman Lear, and investor Lawrence Benenson.
Another example is TaxMeNow, a lobby group founded in 2021 by young multimillionaires in Germany, Austria, and Switzerland which also advocates for higher wealth taxation. Its most famous member is the 32-year old Marlene Engelhorn, descendant of Friedrich Engelhorn, founder of German pharma giant BASF. She recently set up a council made up of 50 randomly selected Austrian citizens to decide what should happen to her €25 million inheritance. “I have inherited a fortune, and therefore power, without having done anything for it,” she said in a statement. “If politicians don’t do their job and redistribute, then I have to redistribute my wealth myself.”
Earlier this year, Patriotic Millionaires, TaxMeNow, Oxfam, and another activist group called Millionaires For Humanity formed a coalition called Proud to Pay More, and addressed a letter to global leaders during the annual gathering of the World Economic Forum in Davos. Signed by hundreds of high-net-worth individuals—including heiress Valerie Rockefeller, actor Simon Pegg, and filmmaker Richard Curtis—the letter stated: “We all know that ‘trickle down economics’ has not translated into reality. Instead it has given us stagnating wages, crumbling infrastructure, failing public services, and destabilized the very institution of democracy.” It concluded: “We ask you to take this necessary and inevitable step before it’s too late. Make your countries proud. Tax extreme wealth.” In 2025, thanks to the nascent movement of activist millionaires, these calls will grow even louder.
