Good question, and I think the answer depends on the society you're from.
The young people can do it out of general 'conditioning,' meaning they were simply brought up around it, or else its a form of rebellion.
In any case, whether rebelling or just having been conditioned to do it, there is a 'shock factor' in swearing that gives whatever you're saying a sharp point.
Notice though how swearing is not always 'appropriate' and in proper 'social graces' someone might not swear in a position where they think it is not appropriate; in a situation they are comfortable however, social graces go out the window.
So to answer your question, I think that swearing is just a social trend spread by far-reaching media. It's almost faddish.
