Fix the problem where a CEO thinks they're worth 300x more than their lowest paid employee, and where banks are giving them massive "lifestyle loans" based on the value of the company stock that they hold to evade taxes and claim their net worth. All the sharks living off of such loans become big paper tigers and liabilities for the banksters if they're unable to control their stock's price through manipulative means. Quit letting them easily do buybacks, get IPO rules changed, and all the other shit they do to artificially inflate/prop up the stock price and this patently corrupt system will collapse.
Oh wait, that requires having politicians who aren't bought and paid for thanks to lobbying and Citizens United. Yeah, we're fucked.
