Statistically i havnt a clue, but i just get the genral feeling its going that way.
Me being 19, i know we didnt do half the things young kids are allowed to over the past few years.
I mean i hear about, kid beating kids for fun, 3-5 year olds swearing, gun crime, verbal and even on occasions physical abbuse to teachers. Among other things.
I think this is becomming more of a problem in the UK, im not awear of what's happning in the US though.
I do think that parents hold 80-90% of the responsobility (IMO) but other things do come in to it, like social life and media, but that can be dealt with by the parents, and teachers, it would be better though if some parents would learn the new parenting skills of this day and age, because they are relying on rules that are too old and not relevent.
Again statistically i dont know, but this is just from my observation, and what ive seen, and heard/read about.
Perhaps it maybe individuals are becoming more careless and not the contry as a whole, but i do get the feeling that some action is needed.
Another thing, obisity, (from a news report i heard a while ago) is on the increase too, not just adults but children are finding the lifestyle of take-aways, tv, gamming, the norm. And IMO this is another thing contributing to there behavior and mind frame.
