Earlier quoted context omitted.
I think you are right about everything but the timescale: the current generation of kids already grew up under constant surveillance...by their parents. When I grew up, during evenings weekends and holidays, kids ran around in the neighborhood with their friends from sunup to sundown. Outside of mealtimes, parents had no idea where we were. A generation later and parents started to time-box everything their kids do,…
How did the "free range" generation (before it was unusual enough to even have a name) turn into the overbearing parenting generation?
1) Ambition for kids to get into the right preschool so they can get into Harvard or whatever, causing more parents to put their kids in 'enriching' scheduled activities.
2) Unreasonable fear fueled by the media. Ironically, stranger child abduction gas been declining steadily for decades and is at an all time low.
This has effectively removed more free range kids to the point now that if you wanted your kids to go play outside, they wouldn't find any other kids out there to play with.
This is why I call it a reverse network effect. The value in playing outside for a kid is now lower since there are fewer potential playmates out there.
