So if there should not be billionaires, who decides where the money goes when a person crosses the line of millionaire into billionaire?
Obviously, those who believe there should not be billionaires, want to empower a governing body with the ability to control people's wealth. We of course have that now through mandated taxes, but we are unlimited in what we can earn.
Imagine being told by the government that there is a limit to how much you can earn, and anything over a certain amount will be taken from you. I will never be a billionaire, but I do not want to live in a country that stifles innovation and production by deciding someone else's limits.
