Yes we have the right to choose, but you're wrong about the other part. Most of us CAN'T quit our jobs and find something that pays better. That's why we have the jobs we have in the first place. If we could all have better paying jobs then nobody would be making min. wage and nobody would work at McDonalds. Teachers is a perfect example of that. If a teacher was to quit where the heck are they possibly going to go and make more money besides teaching without spending tons more money going to college all over again?
I know our system COULD be worse, but it also could be better.
But there lies the problem. The market is supply and demand based. An Actor/Athlete's wage is determined by the demand. We, the consumer, set the demand. While there are actors/athletes similar to the ones in demand, there isnt an exact duplicate (Darrel Hammond does a wicked Sean Connery impersonation, but I dont think Darrel Hammond can pull off roles like the Longest Day, James Bond, et al), so the supply of the actor/athlete is short.
The only way you can achieve a shift would be to decrease demand or increase supply of actors/athletes and increase demand/decrease supply of John Q Publics.
