Problem is that the 'owners' have very little say in executive compensation as I understand it. Corporations are run by a managerial class which determines it's own pay rate. There's always pressure to keep the pay of the working class of a company at a minimal level but very little or no pressure to keep managerial compensation at a comparable level. There's always some general sense in the air that unions are pushing up worker pay above competitive levels but very little scuttlebutt about managers raising their own pay.
Mondaragon cooperatives deal with the problem by having set 'pay rates' based on multiples of the lowest pay rate and the whole corporation having a vote when those multiples are changed.
If I was a shareholder in something like AIG, I'd want managerial salaries set at some multiple of lowest paid worker salaries with any change in those multiples being approved by shareholders.
