As I regularly get misinterpreted (in part my own fault of course), I should restate again that when I talk about "cities" and "urban areas" versus the stereotypical suburbs I'm not just talking about Manhattan, or even the cosmopolitan metropolis that is Fluffya, PA, but any area which manages to possess to some degree urban features such as walkability, sufficient density to support street level retail, mixed use development, mass transit compatibility, reduction in automobile dependence, etc. Such things can exist in various forms and degrees in Manhattan, in small towns, in smaller cities, in older and in better designed newer suburbs, etc.
And I've long thought that many smaller industrial cities had a great potential for revival.
