It's not even the salaries and cash so much as the equity and stock options they get their real power from. It's pretty rare even at megacorporations for the salary component of their compensation to be higher than US$2m per year. The most money you should end up with at the end of 40 years of labor is like US$80m and that's if you're a CEO from like age 25-65. Where are all these mega-rich billionaires coming from (it's the equity).

US$2m is still very high, but if you abolish equity and private investment they can't do much with it anyway. We could see how that plays out and make further adjustments as needed.
