Salary Caps on Corporate Executives

Implement a system where government subsidizes only corporations that keep salary caps at $400K/yr for their CEOs and no exec makes any more than that. Government can give these corporation incentive tax breaks and Corporations that don't adhere to the rule will get tax penalties. Tax payers members of working and middle class should get an option of to invest their retirements only to corporations with salary caps, this will create business environment where corporate profits are re-invested into companies rather then cashed out by top executives. All corporations will eventually comply because large part of stock investments comes from retirement and most people will prefer their retirement investment to be in a fair corporation.
