In the US, especially in the north, kids play 10-20 games a year and that’s it. No one plays at the park with friends anymore. If it isn’t a “real” game the kids don’t do it.
I’m only in my 40s but when I was a kid there were always pick up games going on or just kids playing catch, pepper or scrub.
Then there’s the parent’s irrational fear of their babies getting damaged with a hard ball being thrown around. The bats are the stuff nightmares are made of.
