Among many other reasons, as a (USA) taxpayer, I don't understand why society is subsidizing professional sports by running their farm system.
The challenge of equal opportunity (fairness) is better met thru more and better scholastics.
Do you think we should end the art and music "farm system" too?
Thinking about it a bit more, I'm okay with amateur intermural sports. Like wrestling, swimming, track & field. So while I don't know exactly where to draw the line, I'm a hard no on commercialized sports like American gladiator style football, fast pitch baseball, basketball.

Yes, ideally, we should have magnet schools for STEM, humanities, fine arts, performing arts, agrigulture, voc tech, etc. The goal is equal opportunity, helping kids find their niche, not equal outcomes.
