Why do you come up with all this weird shit? You're absolutely right that many of them will get enjoyment out of it. It's what they know, what they're good at, what they can get into a flow state with... But there are thousands who have failed in their wake. Damaged and fucked up, told they're too heavy, not graceful, too tall, the wrong proportions. And even those success stories are forced to deal with the end of their career being around when they can legally start drinking. Even those success stories have been through a system that is very obviously, provably abusive. That is something they will have to deal with in their own way for the rest of their lives.
