If the NBA player union disappeared tomorrow and Lebron was able to renegotiate his contract he still wouldn't be paid close to messi. The player union isn't capping his salary, the salary cap is. One of the things the player union fights for is to increase the salary cap so all of its members can be paid more. This is an example of an union getting its top performers higher salaries, not the inverse like you're suggesting.
