My question, as originally phrased, apparently was going to cause world war three or something like that according to another commenter, so at their behest I reworded it. Maybe something got lost in that effort, but I was trying to ask where you got the idea that anyone thinks that entertainment/sports stars make as much money as they do because of unions? I've never heard of such a thing and it violates everything we know about economics, so where you find fit in this 'revelation' you keep repeating is curious.
I suspect that this drives wages high for highly paid individuals in sport and entertainment.
Note that stars in entertainment, in fields without unions also earn a lot.
