I don’t believe this. I can’t speak for little kids in a large sample size, but the overwhelming majority of high schoolers are doing something extracurricular. It was brought up earlier in this thread: Instead of playing multiple sports year round, kids are focused almost solely on one or two sports, that are now played year round. Even band, cheer, dance, FFA, etc are dedicated year round events. Or, they’re already working at 15. Sometimes 30 or more hours a week. I spent the last three years legally stalking high schoolers and the stereotype of them just doesn’t fit reality.
Of course, I’m 10-20 years behind most of you and we were accused of the same things growing up
