A lot of US kids are forced to sit still whether they're in front of a screen or in a physical classroom. Typically it's better in preschool, but many kindergarteners only get 20 minutes a day to play if that. https://www.nytimes.com/2019/03/05/learning/do-kids-need-rec...
I don’t see how that could possibly work, unless your goal is to create brain dead monkeys.
I went to a K to 12 school for my last 4ish years of HS, and the kindergartners (the kids, not just teachers) were already almost mind-dead cult like in "Prep for the test!" and "Go $TEAM!".
There were a couple really good teachers across all levels of the school, but not enough.
