The Punk stuff reminds me of a big article done in far-lefty journal Jacobin a few months ago about wrestling in the 20th Century.
If you can distance yourself from the explicit political agenda of the piece (Wresters of the world, unite!), you'll still find numerous instances of wrestling management screwing over talent (the Dynamite Kid stuff is hard to read)

Full disclosure; I'm not a big fan of unions, especially ones with compulsory membership. But on balance a pro-wrestling Union would be a good thing in WWE.
