Some (including me) would argue that "elite travel teams" and the like should not even exist at this level.
Gotta start disincentivizing this at the public university level.
Worse, it's a pipelined thing. If you're not already one of the best kids in your area by the time you get to high school, you won't get any playing time, so you won't get scouted. If you aren't one of the best kids in your area by the time you get to travel-ball age, you won't get any playing time, so you won't get the experience to be able to make the high school team. If you don't get on (or fall off of) the fast track, you have absolutely no shot.
Undrafted free agents sometimes make it to the NFL, and walk-ons at the college level aren't unheard of. You can learn basketball up to an NBA level relatively late, so long as you're one of the incredibly few people with the genetics to make that an option. But baseball is so dependent on ingrained muscle-memory and top coaching that you absolutely cannot start playing baseball at a high level late and hope to compete. And as long as there's money in it at the end of the pipe, there will be competition at the beginning of the pipe.
