Rude Rude Rude

Why do we live in a such a rude society. Is it because we are just living our lives too fast? Are we bringing our children up to be ill-mannered and foul mouthed? Whatever the causes rudeness is on the increase and not just in the UK, I found this article about the increase of rudeness ib American society. There are some books on the subject that have been published recently but I am too rude to read them.
