Parents were failing to do better when I was a kid and we didn't yet have home computers. GenX were notoriously latchkey kids.

If we want parents to do better, we have to reduce the hours of the workweek, say, to below twenty so they have energy and time to parent.

And create community units to replace the extended family. The proverbial village.

That said, if the kids are crazy, the ongoing lack of care and intergenerational mental illness (since before the Silent generation) are to blame, not screen time. But pundits don't really want to look at that.
