I have noticed that community organisations now are far more dependant on retired peopke than they were a few decades ago.
I had one working parent and I had a community because I had places to go.
My 5 kids had 1 parent at home full time and zero community. For most hours they were trapped in a building with adults. Sometimes they were contained in some highly limited adult-made program. And that was what they had. Also most every other kid.
Your 1-parent childhood may still have benefited from having many other stay-at-home parents keeping an eye out the window an ear to street for kids who need attention, and likewise your kids childhood may have been more isolated for the lack of that, even with a parent staying at home for them individually.
Sometimes, it's not about the circumstances of one's own home so much as about the prevailing circumstances (and expectations) of the community as a whole.
We lived that community "norm" as part of a very immersive and busy religious life. We also lived it in modern times where kids moved from one adult-constructed environment to another.
The author's theoretical mental health magic didn't materialize. These kids weren't surrounded with spaces to go with their peers and develop the critical skills that arise when adults aren't available.
This is exactly it. The mental health we're looking for is the byproduct of a childhood spent with regular access to hours-long, adult-free peer time. It also reduces parenting from the stupidly impossible amount of hours we have now.
The community part we're trying to replace with religious spaces was when kids grew up surrounded by multi-generational households. Until the 1st ½ of 1900s, it was what we could count on neighborhoods, villages, settlements, etc being built out of.
Religion can't replace that. I know because my kids grew up in the ideal the author is has in his head.
if two parents worked 20-30 hours a week each, probably not as big a deal.
(I doubt it's a big deal. But we could get the data to at least look for correlations.)
