Having taught unruly 7th graders, I can tell you that the 6 things he teaches are necessary to control a large number of children. And yes, you need to control them, because otherwise the parents will sue you.
The unsolvable problem is that in this day and age, both parents work. It used to be that the mother would take care of the kids, but now they have to be passed off to a third party, who necessarily must take care of several times the number of children found in the average American home.
What kids really need- and do best with- is individual attention. There's no way to get that kind of attention with both parents in the workforce; the numbers just don't work out.
That's your real problem.
