Yes, it is. In more ways than one.
CEO's get paid exactly what their respective worth is, when viewed by the company - no more, no less.
But who determines that worth? In a publicly-owned corporation, that would be the collective stockholders.
Most corporations have their largest shareholders on the "board," but these stockholders still tend to be a small minority of the total stock outstanding.
Basically, the President has called for a stockholder revolt in large corporations, and he is suggesting the revolt should take the following form:
1. If you don't understand why the CEO is getting paid what he is, dump the stock.
2. If you understand why the CEO is getting paid what he is and you don't agree, dump the stock.
3. If your CEO wants a raise, and you don't understand why, dump the stock.
4. Or in the alternative to items 1 through 3, vote the Chairman of the Board out of his position unless the CEO is removed.
In other words - be citizens, not spectators.
