Unfortunately there is little you can do about this. They can decide to give special raises to people and then give the rest a story that "harsh economic conditions" exist and therefore most will not receive any raises or bonuses... however... if those not receiving bonuses all happen to be, for example, Black, Jewish, Hispanic, etc. then it is possible that there might be a cause of action for discrimination.
If you think this is bad, you should take a look at the remaining dot coms and technology companies. I have heard stories about CEOs building gyms within the company, executive office suites, etc. while laying off 1/4-1/2 the work force. If the shareholders only knew there would be a lynch mob... but there is little that you can do legally in most circumstances like this...
