Well it's no use bewailing the loss of the cane in school.
That horse has bolted and the stable door is firmly locked.
Society is going to have to deal with the consequences of children who have no respect for authority until it's too late and they have been expelled with a ruined and botched education trying to find a job(if they can be bothered) without the necessary qualifications.
I take comfort from the fact that most children do turn out ok..and do become pretty good adults.
