It's the Curse of the Exotic that so many prosperous societies suffer from; the same instinct that once compelled Europeans to write entire sagas on the fantastic machinations of despicable Sultans and their utterly reprehensible excesses now galvanizes the modern, more subtle intrigue that has birthed cyberpunk, YA fiction, and other works that depict incredibly abject settings, not because we have some sort of masochistic obsession with dystopian depravity, but because such horrifying conditions--whether they be economic, cultural, or political--are just so alien when juxtaposed with our mundane affluence.
I'd go with "mundane lives" rather than "mundane affluence" - do Midwestern assembly line chicken-gutters not read YA fiction?
