You hear similar complaints given about high paid CEO's. Here is one thing that such complainers don't consider... If a rich CEO or athlete fails to receive a lot of money,
it doesn't follow that you will get the money instead. The person complaining about Bill Gates making lots of money isn't likely to make a dime more even if the government were to put a limit on the amount of money that Bill Gates could make. Easy lessons like this make Capitalism fun to learn.
