I'm mid-60's and remember having to sit in the corner as punishment. It obviously worked! We were also expected to do our chores and there was a cost for infractions. To this day, I make my bed every day, clean weekly, abhor clutter and messiness and turned out to be a pretty good cook.
When I taught in a Christian school, the other teachers would ask me all the time how I was able to get my students so well-behaved. It was simple...I gave them the rules as well as the consequences for breaking the rules from day one. The new kids, of course, challenged me but after a few weeks they understood that I would not let anyone get away with it. Perhaps that is what's missing with today's children. Parents who don't consistently enforce their own rules quickly teach them that they can get away with anything if they persist and outlast them. Parents who don't take the time to teach obedience to their authority end up raising children who won't respect ANY authority as adults. ANTIFA is most likely made up of such people!
The author isn't anti-American at all, since she's written enough on the things which she thinks are better in the US, though they are not necessarily about upbringing children.
