He just suggested a basic income for everybody. I just wanted to point this out in case people missed it when skimming.
oops, i accidentally published an earlier draft. i added a bit more of my thinking here--my sense is that it would probably lead to less waste than current systems. i'm also not sure it's the right approach, but i haven't heard any better ideas yet.
Progressive tax on incomes >$1,000,000. This won't slow anyone down except the ultra-wealthy.
As of 2009, it's 236,883 people. That's less than 1 in a thousand. With more income in a single year than most people in the U.S. earn in a lifetime, they'll certainly still be much more than quite comfortable.
