Yes. My perspective is skewed though. I know it as a child who didn't know any better, and now as an adult Americanized outsider with ties that keep weakening with time, exacerbated by differences in culture. While some things have stayed the same, a lot has also changed since I lived there.
Anywhere is livable, if you either don't have a choice or you're ignorant of alternatives. Looking at it as an American, parts are definitely livable as long as you don't mind the pollution.
