Taxing the ultra-rich would provide 200 million for defense EU advisers say a minimum tax on the ultra-rich is an important source of revenue to fund European priorities, especially defense.

Iirc a minimum tax would mean "it doesn't matter what other loopholes and tax breaks you found this year, you have to pay at least this much because you're this rich". Revenue/profit is complicated, we need to tax mega-wealth like we tax houses.

Tax the rich like normal people with more brackets, tax the ultra rich and corporations with minimums for value and maximums for personal wealth after which the rest is forfeited/of no use.
