It was also my impression that kids who were physically disciplined at home tended to be more violent at school - most of these came from the middle type homes and farms of the time, so poverty was not a big factor.
Really, I can remember at primary school the very first ever child to be expelled in the schools history was a child who's parents didn't believe in smacking him (pretty unusual back in those days). Ironic since he was more than happy to take to other kids with hockey sticks etc... I used to think a good smack or two from his parents was just what he needed.
