Without having read the books or knowing too much what the movie is about, I'd say perhaps the biggest thing is it appears to be a parable to events happening to us at this time.
Again, I really haven't a clue other than one or two things I've read that seemed to suggest there's a ruling class which makes me think of the whole 99% thing and the stories we hear of people doing the things they do to get by.
There's also the whole "reality" tv angle to which this might be some form of commentary on - Survivor to the extreme.
Just a couple of hunches from what little I know, both of which the movie could be seen as a reflection of society in a meaningful way we may not otherwise consider.
