The top earning actors and athletes in the country all have strong union representation, but for some reason it's software engineers who think "nah we are too well paid".
Well, at the risk of getting all tinfoil hat conspiracy theory, I can’t help but wonder if the people posting these “you guys are too well paid to have any other concerns” types are really practicing software developers and not “startup founders”.
Professional athletes in the US need unions because the leagues are granted a legal monopoly. AFAIK most European soccer professionals (where there is more options and competition between leagues) do not have player unions / Collective Bargaining Agreements.
Interesting - as I said I'm not too familiar with the EPL/other euro leagues. When I had tried to google Football unions I did find that PFA wiki, but couldn't tell if they actually are involved in collective bargaining with the leagues. As far as I could tell, no such agreement existed?
