I know what you're thinking but there's so many wrong with them, you're just another sad "the good old days" kind of people that have been proven wrong throughout the history of the world.
Capitalism is part of human evolution, obviously I don't mean biologically, the point here is that it has passed the nature test and become adopted world wide not without reasons, other methods largely didn't survive, so there's no point in arguing against it, or if you do, try move to North Korea kind of place or sort of, what? You don't like it? Bingo.
Sports should not be business? Then quit following sports. Again it's evolution, heck, how did these clubs even got big in the 1st place? Because humanity favor the champions? Exactly, and you can't stop it because that's the nature, only in dictatorship you can possibly force people not to dispropotionally support big clubs, even then that may not even work.
It's just natural evolution, and what we have now already filtered with all kind of filters, not ideal, but that's how this existence works.
