I've often said we don't need billionaires. That when one reaches that milestone anything above $999,999,999 should be taken as taxes from that person.
When I say this people often become defensive saying that the government shouldn't be able to dictate how much wealth one person can accumulate. (It also happens that many of these people are prolife but that's neither here nor there.) Often times comparing this action to communism which of course it isn't.
The issue of course is that many people don't understand what a billion of anything is. The human brain can't comprehend such massive numbers. But nevertheless, there are people that are approaching the trillion dollar mark a number even further removed from a billion by several magnitudes.
Should there be billionaires. Probably not... What do you think?
