I believe that we are in the middle of a social engineering program with those who think that by eliminating any form of physical punishment for children that we will eliminate all violence.
We shall see what we will see.Already children have become more unruly in the classroom.Not all the unruly element come from poor deprived backgrounds either.Quite a few have good homes with caring parents,and theoretically know right from wrong.It's just that no one is saying no emphatically enough.
However this is still a minority of the population and the world we live in are still the safest it has been in the last 1000 years.
