Spare the rod and spoil the child.
While this might be a case of being extreme opposite from the "absolutely no corporal punishment" tendancy prevlent in the US today, I honestly believe that some of the fear based parenting (spankings and the threat of) is still required and the solution of the whole mess with children, teens and young adults behaving like they do today.
We simply can't put our children in overprotective cocoons while putting our teachers and the Education System in a straight jacket and expect them to turn out normal.
