Everyone's generation always talks about "today's youth" being wilder, ruder, generally less civilised than their own used to be. I think you'll find your grandparents very likely said the same about you.
As a student of History I can state that this seems to be a cyclical occurrence, having happened ever since there were young people and old people, i.e. forever.
Every ageing generation talks about a 'golden age' or something similar when they used to be young "without all these damn whipper-snappers running about!"
I'm not saying that today's youth aren't wilder, ruder and generally less civilised than the previous generation, but I am saying that you have to apply some perspective to the issue.
When I am 60+ I'm sure I'll be moaning and groaning about what music kids will be listening to, about how much better behaved we all were when we were young etc.
Yes there's certainly a sense of declining morals and manners, but again I shall say, there has always been! From 17th Century gentry complaining that the youth of their day were indulging in the new habits of drinking coffee and reading newspapers (the horror, the shame!) to 1920s/30s born parents complaining about LSD, Cannabis and black people in the 1960s. (Excuse the generalisations, but the point remains.)
Guess what, most young people are immature! They don't want to learn the responsibilities and wisdoms that usually only come with age, they're too busy thinking up new ways to piss you off!
They might well be annoying, but they're going to be the ones running the country, developing new technology, and giving you medical care when you're too old and decrepit to move around any more.
It's just life. The same issues have been around since before BC/AD was even conceived of. If every generation is 'worse' than its previous, then how have we made it to the year 2010 without blowing up the entire planet? Oh right I forgot, young people grow up! Most of them anyway...
Edit: Now to wait for the expected cliched negative responses... Just like I would reply if I was an older member of society reading this. Proves my point quite nicely in fact.
