ehh, corporate billionaires getting most their billions from stock compensation, if you create a company that goes on to be worth 10's-100's of billions of dollars, why shouldn't you be a billionaire? it aint about big dog salary vs little guy salaries. finance billionaires are paid bonuses on the growth of their portfolios or ROI from investments, also makes sense. real estate magnates, the same. then you have inherited wealth that had time to grow. all of these make sense that billionaires would come from it. now if you want billionaires gone, then you need to disrupt the path that creates them, not get rid of them or say "you can't have more than $xxxM in wealth."
i actually think we need to stop fixating on bill/millionaires, other than them paying more taxes, we need to come down harder on business entities and get middle income salaries to where they need to be, stop the debt snowball working class/middle class people get into as they try to move up, etc
