Some say there shouldn't be any billionaires. This seems like it would ensure that. Would this be better than the status quo?
It seems to me a 100% wealth tax is a bit dumb, when there exists a more obvious alternative known as expropriation. In case your intention is not to expropriate or confiscate, but rather ensure there are no billionaires, you should implement a special wealth tax designed for that purpose with a rate below 100%. I guess the rate should be variable, depending on the wealth of every billionaire
