On the other hand, you're not going to find the best and brightest executives if you're paying them the same rate as low-end football players / baseball players or what many TV stars earn in a single episode...
I guess that depends on their motivation. You're a successful CEO - wouldn't you enjoy the challenge of turning around a once-failing company? The prestige alone would guarantee a healthy salary for your next role.
It would make an interesting seperate discussion.
In my limited experience, people are motivated by money, fame, or power (or some combination).
I'm not motivated at all by fame. Could care less. I am mainly motivated by a form of power - freedom for myself.
