In the end it's only an issue because it's easy for politicians to rally crowds about it, financially it doesn't make all that much difference. But on the flip side, why should it matter all that much to a CxO that's already making more money than he or his children could spend in their lifetimes.
Some CEOs are worth what they make and some aren't, I think it's just a fact of life. I'll say that Eric Schmidt is worth of penny of his $1 salary
