I do not.
There have always been inadequate parents.
Their kids will always have misbehaved at home.
Now the kids misbehave at school and in the street as well.
People do not change. We must look elsewhere for the cause.

Schools used to do a good job of instilling a respect for authority at an early and formative stage, whatever the home situation.
Now they just try to be nice and friendly, then hope the parents can help when the kids go wrong.
Usually they can't.
