The respective leagues should be forced to foot the bill in baseball, basketball and especially football. The vast majority of the money will be going to players in those sports. The NFL, the most profitable sports league in the world, pays next to nothing for scouting or player development. They get ready-made players subsidized by the government.
In soccer (real football) a team will have hundreds of scouts all over the globe. Kids get signed at 6yo, their first professional contract at 14yo. Their education, housing, food, transportation ... all paid by the club for years. It's common for their parents to become employees of the club. Very few of those kids ever make it to the first team. Players development is a giant money sink for every club.
Compare that to the NFL. Maybe a half dozen "scouts" who evaluate adults that already have hundreds of hour of tape. The hottest prospects get put on franchise contracts where the player doesn't have negotiating power. The lesser players are on contracts where they can be cut or traded at anytime. The teams take on zero risk. No deployment leagues, no deployment teams to pay for. No relegation. No incentive to even win since all the profits are shared. The worst teams get the best players who are forced to join poorly performing clubs. To call it communism is an insult to communists.
