One thing about these dystopia YA novels that has me scratch my head is what is the rest of the world doing. I know the Uglies briefly touches on it but I find it interesting that the dystopia typically is very U.S.-centric.
Yes, it is shocking to see anything US-centric in popular culture.
Not a HUGE deviation (still firmly western-world) but John Christopher was all about the YA dystopias, and his stuff is set in Britain/Europe. (To be clear, this is a shout-out to a particular favorite childhood author, not a denial of the US-centrism of a lot of YA. I would be totally into more non-US dystopia YA.)
