I read only a few of the posts but they seem to imply it's the fault of the parents - helicoptering, snowploughing, and what not.
Well, there are some parents who are failing their children (and impacting schools) but those are not involved parents. Parents who lack emotional intelligence (often due to their parents) and are either too strict, too permissive, or neglectful with their kids.
Most parents however are involved, good parents who are taking onboard all new research on child development, all that we have been learning about ND, trying to navigate a very different, over stimulating modern digital world.
The way we treat children now is generally very different to a few decades ago, and that is not a bad thing.
The issue is the schools have not caught up. Without getting into much detail to everything that's wrong with them for today's world, my suggestions for improvement would be-
-easier curriculum - less academics and more practical, everyday skills
-emphasis on play and wellbeing
-shorter weeks at schools (4 days?) and/or shorter days (pick up at lunch)
Yes, not good for the economy, as that will mean either of the parents being around to actually be with the child/ren for a substantial time.
Good for society in the long term though, imo, better regulated children, better mental health, less crime...
Definitely solving the issue with the pressure on schools.
