Solid observations.
I think once you go above 4 kids, the older ones start legitimately helping to raise the young ones cause the parents attention gets too stretched.
It really comes down to what the parents are into and whether the kids are interested in that at all. When I build things on the homestead only one of my kids reliably comes to “help” and try to learn. Same with the garden, only one has any interest in helping my wife when she’s out there. They’re still young, so we let them choose their own adventures and don’t force anything on them
When they’re teenagers there will be non-negotiable life skills that they need a baseline knowledge of to go out in the world with
Screens certainly play a negative role these days if the parents allow them to be a babysitter. That’s a shortsighted approach and somewhat of a Faustian bargain if you ask me
Some “free” time for the parents when the kids are young- but much less focus, interest in the little things of life, and deep creativity to entertain themselves and play freely for the kids.
When I see kids in a grocery store cart or at a restaurant with a screen in front of their face I feel so bad for that kid, cause they are getting almost zero data points from the real world around them
