You'd have to either kill football or get the fields by pushing out the triple alliance of baseball (dying)/track & field (also in remission but USATF still has a lot of clout because of the Olympics)/lacrosse (unusually dominant in the East).Thanks for these clarifying replies. Sadly, the cannon fodder argument seems the most logical explanation. MLS Next has 15,000 players for the 23/24 season. That's 15,000 kids walled off from the many social/psychological/personal benefits of high school soccer, all so that a couple dozen (??) can be developed for professional contracts and the national team. Compare that to basketball, which also has a dominant, talent-driven club system, but which encourages high school competition, which is awesome all across the country, and which doesn't ruin any player's development. Imagine how awesome high school soccer could be if US Soccer and the MLS invested in it. If the best club coaches also coached in schools. If the most talented generation of teenage soccer players actually played for their schools. You want to grow the game at home? You want fans at MLS games? You want NCAA soccer to feel relevant? Start by filling the stands at high school games, with an exciting product on the field. Give teenagers something to care about and cheer for. What a strange missed opportunity by the people in charge of developing soccer in this country.
I've also gotten a peek at life in gridiron football at the top 25 SoCal high schools (almost all overwhelmingly private or parochial). Soccer ain't got nothing on the shenanigans going on there. Everything from scholarship money being thrown and transfer window abuse (people literally renting out places to say they changed zip codes), steroids (my guess is 25% of the athletes are on them), cheating when it comes to grade limits in which teachers are actively involved, and abuse. Scary...high school sports in general aren't like when you were growing up (even if you are a later day Millennial). Still, I get your point...the reason football despite all the political issues and concussion concerns is alive and kicking is because of the high school experience.
