Time for De-Billionairization?

Pro: Billionaires wealth give them too much power and human weakness cannot be trusted with it. Wealth should be judged based on the good a person does, not the money he or she has.  It would be possible to allow entrepreneurs to retain equity control of successful corporations without them having the money part of it. That might even be attractive-- a class of stock where the value is sold and rises and falls, but the equity is retained by the founder.

Cons: Money motivates innovation and investment.

Debillionairization could be done by legislation gradually implemented, so no new billionaires could evolve and no billionaires could leave descendants billion dollar fortunes.
