The long term psychological and physical effects from children not socializing for many months up to several years are not known. Not picking a side here, being a teacher, I still am on the fence, but if you think kids are not socializing with other kids, drive around a little bit. They are everyplace. Big kids, little kids, kids of all ages are with each other socially. I see it somewhat but not anywhere near as before. My guess would be the majority of kids have minimal to no activity with other kids outside their immediate family. I have a son playing tournament baseball but outside of that has not been around other kids.
