A couple of points.

1) As for them being stars of the business world and similar to stars of the sports world - fair enough - but Sidney Crosby has to negotiate against a club that wants to keep his compensation down (for several reasons, including impacting what it has to pay other players and a salary cap).  For too many CEO's the arrangement is not adversarial, it is instead quite chummy, negotiating with a group of people who often have a vested interest in seeing the compensation go up.
2) There is no way that a large portion of their income (stock options etc.) should be taxed at a much lower rate than their salary. In effect we are all subsidizing their wealth.
3) While it may be true that if they don't perform they get canned (doesn't happen as often as it should) their wealth and the golden parachute often attached to such a dismissal insulate them from the consequences of their actions in a manner that the person on the factory floor can only dream about.
