Share of taxes paid by the top 10% in the U.S. vs. other countries

From Cafe Hayek.

"from page 54 of economists Phil Gramm’s, Robert Ekelund’s, and John Early’s excellent 2022 book, The Myth of American Inequality: How Government Biases Policy Debate (footnote deleted):

The top 10 percent of households in the United States earn about 33.5 percent of all income, but they pay 45.1 percent of income-related taxes, including Social Security and Medicare taxes. In other words, their share of all income-related taxes is 1.35 times larger than their share of income. That is the most progressive income tax share of any OECD nation. In Germany, the top 10 percent earn 29.2 percent of the income and pay 31.2 percent of income-related taxes, 1.07 times their share of income. The French top 10 percent earn 25.5 percent of the income and pay 28.0 percent of the income taxes, 1.10 times their share of income."
