So actors are overpaid? Think about some movies where a single actor can bring in $250 million for the film he/she is in. Don't you think they deserve a good cut of that?
Would you be happy in hour job knowing that you singlehandedly brought in a quarter billion dollar and you get $50K for it? Wouldn't you expect more?
The movie business is unique. A movie can cost $5 million or $250 million to make yet the movie ticket remains the same price for both. Name any other business that works this way?
