So then why don’t we tax all personal incomes above a certain threshold at 100% and redistribute it. You are quite correct, there really is no need for anyone to have a $Billion in Assets or earn and receive even an income of multi-million of dollars a year. The problem is that you remove this reward and many people loose their drive and the economy collapses…USSR, and even in this case there were oligarchs that had a lot of wealth. It is virtually impossible to eliminate greed.
