INCOME of Celebrities and Athletes!!!!!!

When I hear about the income made by celebrities and athletes even for just one movie, game or fight... seriously baffles me. It also makes me angry. I know that they of course earn and deserve their fair share, but millions for one boxing match?! .... seriously!?? For example... the Potential McGreggor vs. Mayweather fight. If all goes through, each will get about 100 million each!!!! There is so much poverty in our country alone, as well as in the world that this sort of money for a single person, to me is crazy! I know that more goes into it, but I still believe THAT much money is not necessary. I do also know that many do contribute quite a bit to charities, but many don't. Before anyone may say that I should help if I want to say anything about it, I do in a few ways. This thought (today) was triggered by watching the movie Lion.  What do you all think?
