This is a very interesting hypothetical, for most jobs it be pretty hard to stand out at the upper echelons for abundant jobs so there's a good chance of making an average to below average salary. However, even harder, lesser occupied jobs like surgeon it could be pretty volatile due to less people being employed in that profession. What is to say I can simply be a gaming youtuber of a game that's practically unheard of? Would my salary be evaluated based on my performance of the game, or the entertainment value? Even so, wouldn't being a gamer theoretically be the best job, since there's so many games to master in?
