Theres very little respect from young teenagers for their elders, whether thats always been the case is dubious . In the 60/70s and before perhaps if you were out of line a teacher or a parent gave you a clip round the ear or a beating. Those who were given the power of corporal punishment often abused it, i.e teachers beating students for nothing inparticular, very human trait of abusing any delegated power, and in an attempt to rectify that we've overshot the other way and you cant touch a kid without being sued, or sacked or labelled a paedophile. You give a kid whose out of line a clip round the ear and their parents will be around and in your face where before perhaps if you came home and said so and so gave me a whack youd get asked why and maybe get another one from your parents!. Somehow somewhere people lost respect for each other, and maybe thats where the Thatcher argument comes in. But eitherway, kids are now untouchable, and they know it.
The problem truly begins at home though, I believe.
