Teenagers don't need solitary enrichment. They need places to hang around with other teenagers. That's what they used social media for. Now we've taken away social media, but we, the adults, haven't rebuilt places where teenagers can hang out together.

Invite your buddies over - your parents are nervously hovering. Hang out at the park - adults find you strange and might call the cops. Schools close at 3, malls gone, libraries full of homeless people.

What's going to happen is the rich kids will be fine, shuttled around from activity to activity. And the poor kids, the kids who used their phones as escapes from dull, grey homes - they'll suffer.
