What IS the "new school"???
To my knowlege, kids haven't changed, just they way they are handled. I don't think it's been a big improvement. OS works. It's tried and true most of the time. HOWEVER (aha, the caveat) - there are things I'VE learned over the years. Those are new school (to me).
AND... (another caveat) - society is different than it was 30 years ago or more. So things ARE different whether we want them to be or not. Therefore the way we handle some things is, by necessity, different.
I don't think I answered the question.....
