Because it's professional sports being done by universities, whose mission is entirely different from professional sports. And most of these universities are public universities. Why in the hell are universities doing pro sports?'
I'm in favor of pro athletes getting paid whatever the market will bear. That said, sometimes, as in actual pro sports like the NFL, the players get more than the market will bear, as do the owners, because they use their power to do things like get the taxpayers to pay for the stadium from which the owners and players benefit, and that sort of thing.
That said, there's a lot more laborers out there than pro athletes. And most of the laborers aren't among the top economically, socially or culturally. And IIRC, you're big on the people at the top in charge and not so big on the regular folks. IIRC, you were all over "it came from a wet market," which was an (unsupported) theory that diverted all the blame away from the higher ups in China and the US and towards the regular working class and middle class Chinese people that go to their local market to get dinner. Those Chinese people are laborers. The US & Chinese gov't officials and scientists are not laborers.
And when laborers in the US pointed out that maybe it was the higher ups in the lab that started it rather than regular people at the wet market, people in the giant US media companies, who aren't laborers either, called them dirty names and said they were crazy.
