Could you make a sentence with the word Dystopia?

A Dystopia is the opposite of a utopia. Every dystopia has something in common, a totalitarian government, no freedom of different thinking. Most novels and movies about dystopian worlds denounce errors in the human society. For example: in Fahrenheit 451, the dystopian world shuns knowledge by burning books. In Uglies they make everyone get plastic surgery because the government thinks that everyone is born ugly. In The Hunger Games, the government shows how powerful they are by creating a kid's version of Survivor.

If you could make a dystopian world, what would be its rules? And what errors would you denounce? I think it's a really interesting subject.
