Somewhat of an undervalued point to the bolded is that with these expensive travel leagues comes a massive sense of entitlement....from the parents. A lot of these parents are funding these youth sports for the wrong reasons leading to all sorts of toxicity in the sport. Recent real-world example is my friend's son losing his position (that he earned on merit) to a new kid who got the starting position (worse in all statistical categories) because his rich parents made a substantial donation to the school. When the rich kid inevitably started being a liability on the field and has his starting spot revoked, the parents became enraged and became a cancer to the entire team, including the boys, coaches, and other parents. This, sadly, is the new normal. It's not an outlier and apparently extremely common these days.
So to the bolded, kids who's families actually can afford it, have to deal with levels of bullshit that make it unbearable, further alienating more and more potential participation. People (like me) just flat out refuse to be around that culture and nudge my kid into other activities.
