Why Do People Watch Jersey Shore?

Jersey Shore is basically a show about a group of people who work at a little T-shirt shop, live together, go out and party every night, and just do stupid things.  So why watch it?  What's the point?  I have watched a few episodes and frankly, I was not impressed.  Some people say that the like it because the people are so stupid and it's funny.  I don't find it funny; in fact, I find it sad that these people are getting paid a TON of money just to be on TV and act like complete idiots.  There isn't even really a plot, or a reason for this show.  You pretty much just watch stupid people do stupid stuff.  I mean at least Big Brother has a prize at the end and people leave the show every week.  In Jersey Shore, nobody ever leaves the show, nobody will win anything at the end of the season, it's just a group of people going out and partying or doing some other activity.  And who were these people before Jersey Shore?  Were they famous before this, thus explaining why on Earth I should give a darn about them?  I don't think they were.  So where did they come from?  Why them?  Were they the dumbest people up for the cast list?  I can't answer that, but I know that Jersey Shore should definitely go off the air for good, or our country really will end up as it did in the movie Idiocracy, a movie where Luke Wilson, an average guy, gets frozen for an experiment, forgotten about, then wakes up in the future to a world where he is now the smartest man on the planet because everyone else has gotten extremely stupid.  All I can do is hope, that that is not where we are headed as a society.
