Congratulations, you've discovered Communism. I'm not being facetious when I say this either. That is the exact logical thinking that Karl Marx used to convince and sell people on Communism. He would argue things like this to start the process of grooming people. I went through this exact same process and discussions in grade school. We had this exact discussion to groom us into thinking Communism was a good thing. It's a lead in. It was always a midwit argument.
The reality is, nigger ball players HAVE to get paid that much money. Why? Well, if they didn't and I could get a career and make 60k per year as opposed to playing Niggerball, for a 2 year contract of Niggerball my salary would have to exceed that 60k. Plus the costs of travelling around constantly and security detail as now you're celebrity. However, the most important cost of all: Time and Health. If I'm playing Niggerball for ten years, that's ten years I could be doing a career. Ten years of Niggerball at let's say 60k, is 600,000. So I better be getting paid at least that 600k. Now let's talk about injury. Niggerball players put their bodies at risk and get potentially life altering injuries. Depending on the sport, they straight up have shortened lifespans. Many niggerball players are dropping dead by 60-70 or have serious issues due to the strain on your body. If you don't have wealth, you're absolutely fucked. And what happens then? No one plays Niggerball. Anyone smart, wouldn't play Niggerball. You're reducing your lifespan and subjecting yourself to potentially serious life altering injuries. That burden is all on you. You're taking those millions in exchange for suing the Niggerball League. Which normally would pay out the ass otherwise, but it's cheaper to pay you millions now than leave themselves open to injury lawsuits later.
Everything is the way it is for a reason. Nothing is without a reason. Also, some janitors are paid exceedingly well.
