rich just will move from this scheme to something else, and nothing changes.
The rich will just move to a different country, negotiate with a Swiss canton for a fixed sum tax. I don't see how a tax that punishes wealth is sustainable, the wealth will just go somewhere else.
Maybe if we had a world government or something.
