In Brave New World, Aldous Huxley offers an exploration of what it means for everything to just be... fine, warts and all (spoiler alert: its mostly warts). I'm not sure Huxley quite knows when he's critiqing or advocating the future he describes, but at times that confusion makes the storytelling all the more believable.
It's a quick read, but it requires perseverance. The first few chapters of clunky exposition (in the guise of a montage/tour) nearly put me off entirely, but these are more than made up for by the musings of Mustapha Mond and John the Savage towards the end of the book.
