I just don't buy the demise of our society. I think it has become a little too self centered, especially our politicians, but the vast majority of young ladies that shared the travel ball and college ball journey with my DDs came out just fine (I do have to admit that there seems to be a DQ sprinkled in now and again).
As far as foul language goes, whether in conversation, prose, film or music, over use just seems to me to be lazy. Has more effect, I think, when used as punctuation (again, I have to admit, sometimes the work wouldn't be the same with out it ... Dogma and Boondock Saints come to mind).
A while ago I heard a radio interview with a linguist who had written a book about language and early acquisition of vocabulary, etc and kids start learning these words at age 2 and have pretty much their full complement by age 5.
Curse words are as old as language. Personally, I think using a lot of them just takes away from the content of the discussion, kind of like when posts are consistently packed with typos, bad grammar and wrong words (do have to cut some slack for fat fingered cell phone replies).
Not that the NY Times is a definitive source but the article refers to a lot of the same background material as the interview I heard:

I see no hope for the future of our people if they are dependent on the frivolous youth of today, for certainly all youth are reckless beyond words.
