A good friend of mine at high school was very bright, kind of a troublemaker, diagnosed with ADHD, took prescription Ritalin, was a bit of a pain in the ass with his teachers, but had parents who cared and he ended up graduating and doing fine.
I don't know if they think their children just aren't capable intellectually or what.
There is a whole industry around youth sports that is designed to extract money from parents. That doesn't mean that the kids don't enjoy it though.
How does a parent prioritize their kid growing tall?
I’ve asked this question of some acquaintances that prioritize sports above all else. Their kids play different sports all year around and are on all these traveling teams. I’ve asked them if they seriously think their kids will be good enough to get a college scholarship or play pro sports (I’ve seen them, they won’t be). They just shrug. I have to presume this is how they were raised and so they are doing it to their own kids.
Because in order to even get a shot to play professionally, you have to play well in college, preferably at a notable school. In order to get a shot to play well in a notable college, you have to play well in high school. That means you have to make varsity, play on the team, be a starter. And that usually means you have to be ready to play when you get to high school. And the best way to do that is to play peewee, travel ball, etc.
You'll find out if the kid is coachable, if he can be made coachable, if he's got aptitude, etc.
