I've been involved with a company where the CEO sits by the pool each day sipping mai ties while throwing temper tantrums. This person is supported by the employees, not their leader. When the few that are left, leave, this person will have to do some actual work, and lacking a college education, and having never learned on account of having been surrounded by yes-men for so long...
That's a rather extreme case.
That said: NO ONE's work is worth billions of dollars, I'm sorry. No one's, period. Pragmatism trumps naive and purist notions of "free market capitalism", which only lead to the same kind of dictatorial hegemony we all (rightly) despise in government.
I'm a capitalist and will go to my grave a conservative, but I'm one with a brain, not a mindless free trader.
You sir are a typical envious class warfare proponent. Why do you care how much anyone (other than you) makes or what their lifestyle is? It can only be jealousy. There are lots of people who make or have lots of money, so what? If you work in a company where the CEO makes lots of money I would remind you that you took the job they offered you at the salary they offered. You can quit. You can buy up stock and vote the CEO out or vote for a lower salary. But to suggest that there is some magic formula about how much a CEO can make is just irrational.
