I an not sure I understood this point. Could you please explain when you have a chance?
An actor or athlete is less interested in the long term viability of the "corporation" than his own compensation based on his marketability as a celebrity - well that does describe the worst CEOs out there.
But the athlete/actor is not responsible for the high level management/financing of the entire organization, or the livelihood of the other employees. He is the product, or the producer of the product.
The CEO doesn't produce anything. He is the person responsible for the high level management/financing of the entire organization, AND the livelihood of all the employees.
