idiocracy

in class on monday and wednesday, we got a chance to view the movie "idiocracy".  of course, i want a bit of insight on what you thought about the film.  any comments are welcome, but specifically responses to these two questions:
are we (the US) headed towards an "idiocratic"society?
why does my judge (films writer/director) choose commercialism specifically as one of the main causes of an all-out idiocracy? is it fair?
