I think there has been a marked change in values overall for the this younger generation, but I also understand that I was raised a lot differently than most of my fellow peers. That having been said, I think the most damaging enemy to values have been the legal system. Many states instituted laws which, in essense, tells a teenager that they will not be held personally accountable for their actions, and that the repurcussions of their actions while a teen will be wiped away when they turn 18. They are given a clean slate, irregardless of whatever crimes they did (so long as the laws broken were not Federal). And so the cancer spreads.
If a person is not held responsible for major actions, minor actions will be totally ignored, right?
Other factors, at least in my opinion, include the rise in power of Child and Protective Services, the weakening of schools to inforce discipline without being sued (didn't the teen and parent sign a paper, a contract, allowing the school to discipline a pupil for breaking school rules?), and the sue-happy culture of the late 70's and most of the 80's.
I'm sure there'll be more later.
