To begin reversing the decades-long trend of surging inequality that has weakened democratic institutions and undermined critical programs such as Social Security, Zucman made the case for a minimum tax on billionaires in the U.S. and around the world.
"The idea that billionaires should pay a minimum amount of income tax is not a radical idea," Zucman wrote Friday. "What is radical is continuing to allow the wealthiest people in the world to pay a smaller percentage in income tax than nearly everybody else. In liberal democracies, a wave of political sentiment is building, focused on rooting out the inequality that corrodes societies. A coordinated minimum tax on the super-rich will not fix capitalism. But it is a necessary first step."....

Responding to those who claim a minimum tax would be impractical because “wealth is difficult to value,” Zucman wrote that “this fear is overblown.”...
The last 2 paragraphs seem inconsistent--a tax on wealth is not a min. tax on income. However, from the Times article: "There is a way to make tax dodging less attractive: a global minimum tax. In 2021, more than 130 countries agreed to apply a minimum tax rate of 15 percent on the profits of large multinational companies. So no matter where a company parks its profits, it still has to pay at least a baseline amount of tax under the agreement.... ....another coordinated minimum tax — this one not on corporations, but on billionaires. The idea is simple. Let’s agree that billionaires should pay income taxes equivalent to a small portion — say, 2 percent — of their wealth each year. Someone like Bernard Arnault, who is worth about $210 billion, would have to pay an additional tax equal to roughly $4.2 billion if he pays no income tax. In total, the proposal would allow countries to collect an estimated $250 billion in additional tax revenue per year, which is even more than what the global minimum tax on corporations is expected to add."
