Is The catcher in the rye still relevent today?

I really feel like the Catcher in the rye is no longer relevent today because the book was written a long time ago in the 1950's. Now that it is 2011 a lot of things have changed since then especially in society, none of the same things apply. Plus I feel like today no one has any innocence anymore at all because even at a very young age people have already been exposed to the bad thing in life. No matter what anyone tried to do no one can help try and keep people's innocence. Overall the Catcher in the rye was a very good book but it has absolutly no relevence this day in age, but back in thr fifties I would say yes it would be relevent.
