How do we pay for it? I'd start with a 100% wealth cap tax. Once you have a pre-determined amount of *net* welath (including real estate, stocks, and other non-liquid assets), say $250 mil (more than that just seems like video game points), all income gets taxed at 100%. Sure, you're allowed to have more than the wealth cap, you're just not allowed to make any more. Drop below the cap, and income gets taxed at normal progressive tax rates again.
