I think that is a really underrated driver of the travel ball phenomenon. Lots of affluent people that know they aren't great athletes see it as a way to limit a lot of competition early. Our rec baseball league is terrible, and it's still got a lot of athletes that if all the kids were part of a program looking at development to make the best high school program, those athletes would be selected for development over the the vast majority of the players that have been playing travel ball since 7 or 8 years old. I think a lot of these parents without really acknowledging it, maybe even to themselves, see baseball as a sport you can stack the deck in a way you can't for football or basketball. It's basically golf and baseball, and then tennis, where most good athletes can't pick it up in Jr. high or even early high school and their athleticism trump the fact that other people have been training for years. Soccer is sort of in between. Athleticism still matters more than baseball, but its sort of hit or miss whether a good athlete can quickly catch his ball skills up.
Oh that's 100% the case in our case here. No matter how good the raw athlete, there's technical proficiency necessary that's impossible to just pick up in organized practices. If you don't learn it on your own, you don't learn it.
In my son's case, there were plenty of baseball availabilities everywhere you looked, but the step to the first rung of the city's city-sponsored travel ball team program wasn't taken when it was our opportunity to take it and, once the moment had passed, there was little to zero opportunity to get onto the ladder, even though there were tryouts each summer. The fraternity pledge class was set in elementary school and it would have been a prohibitively-awkward maneuver to join it in motion years down the line.
I sincerely doubt it would have been the happy experience it's been insisted I caused us to miss. My son didn't want to work out at the batting cages on his own time 100 days a year for one thing, so it would have been unfair to the rest of the team to hold a spot through political connection, which I am confident we could have done. He fought his way into school ball at the seventh grade level, and it would be foolish for me to pretend at least some of that didn't play a role then.
FWIW, several of those boys are playing non-Division I college baseball now. You haven't heard of any of them. There's one you may hear of, but probably not. That's a goal only gently talked about along the way, in much the way everyone who buys a lottery ticket says it's just for fun but, have no doubt, that secret, core motivation is there.
Tim Green, who played tight end in the NFL and has written some books, points out there's nothing wrong with dreaming big and dedicating a life to the dreams, and I don't disagree. It's a good life, and fine, but it's not the life my son wanted. He's good friends with several of them and they hang out to hunt and do other things now though, so it's not like they're excluded from his life. He just didn't live in baseball-land with them 250 days a year for several years. Plus, he's very social and makes friends easily - that was more than 50% of his enjoyment of baseball too - so he has no dearth of friends.
