Well, concerning the nothing has changed crowd, I did not know that 20 years ago there were schools were teachers were afraid of their students, in fact, teachers 50 years ago could still cane students on their hands and the students behaved. Nowadays we get the newest horror stories where students hang a teacher out of a window and force her/him to do what they want. It's of course not just the children who changed, they just realized that nowadays with all the social appeasement, they can get what they want through violence and all the adult wusses will be scared and shocked, some years ago all the adults would have caned them for that sort of behaviour.

One more reason to slap your kids reasonably when they deserve it.
