I don't really object to corporate greed, it seems to be the nature of all Americans to earn as much as you can so in a way many of us could be called greedy, not just corporations. And yes, I admit to being greedy myself.
My main criticism would be with companies that continue to reward their executives with bonuses and raises while still taking government aid such as the Bailout monies.
If a corporation is receiving government assistance (our tax dollars) then salaries and bonuses should be frozen and possibly even be cut for all employees, and especially so for corporate officers who by the companies failures mark themselves for mismanagement of the company.
