It’s all involved parents. That’s why there are no longer vocational programs in schools. Parents didn’t want to be told their kid isn’t “college material”. There are completely disengaged parents who don’t care if their kids graduate HS or not.
I think we’re all pretty isolated. We argue over which 9 or 10 rated school is better. Which school has more AP classes available and which HS gives better odds of getting into an Ivy League school or UC Berkeley. Meanwhile 20% of kids aren’t even graduating high school.
I have cousins who grew up in alcoholic and/or divorced parent homes. Most of them didn’t finish HS. They dropped out and eventually got a GED. It’s not that they are dumb. They just had a super chaotic home situation. They were more focused on getting out of that situation than going to school. Most have adjusted as adults, but they started out way behind. My parents tried to help as much as they could, but you can only do so much with addiction. Even if you buy things for the kids, an alcoholic will return them to the store even if they have to accept far less back than was paid for the items. All they care about is getting money for the alcohol.
