I coached my son's soccer team for a few years, and I found that most well-to-do parents around here are putting their kids in highly competitive, selective, and expensive private leagues, even at a very young age (kindergarten).
It's starving the rec leagues of motivated parents who have the time to volunteer.
It's dumb because it's committing the kids to a lot of time and travel despite the fact that 99% of kids are never "going pro."
It also has a segregation vibe to it.
