I actually love Captain Obviously Meta's idea of a society obsessed with dystopian stories! Can you imagine being a young, happy, generally optimistic and well-adjusted individual who just wants to lead a happy life but lives in a society determined to make heroes out of adolescents in extremely unlikely situations? I don't know why, but this appeals to me.
I started writing a kind of dystopian story with a literal grammar police for nanowrimo. That would be taking the prescriptivism in grammar and deterministic ideas about people and statistics ("oh, you're a [ethnicitiy] [social class] [sex]? then you must be X!") present in today's society to an extreme.
So, what flaw in today's society would you pinpoint for a dystopian story?
