Of course it is my call. The economic truth is that these people are overpaid, because they are paid upfront. Give them a share of what they sell.It's your opinion, not your call. They get paid whatever they can get without force or fraud. It's called the free market. Until you become the king, you don't get to make the call, only express your opinion. Which, btw, is goofy.
Goofy or not, it is the approach that Disney took when Ron Howard demanded too much for the making of an "Alamo"movie. If you guarantee the talent too much money, the film is less likely to make money.
