The NBPA has overseen a huge increase in NBA player's wages over the past few decades, both at the top and for the average or minimum player. Yes, there's a salary cap, but that actually helps the vast majority of players, because otherwise Lebron would get paid 200M/year and the minimum/average players would get basically nothing, and it also ensures competitiveness.

A salary cap is not a reason unions are bad when the salary cap is 800x the average person's income...
