My brother coached Little League, Babe Ruth, and HS baseball and he quit all three for the same reasons. He still had the itch to coach, so he ended up coaching girls' HS softball until he retired. He said that they, and their parents, were better behaved than the boys' sports. Somewhere upthread someone mentioned the push to get kids into college sports programs. I think there's some truth to that. Parents are living vicariously through their kids.
As you wrote, the kids are the ones who suffer.
