The original Death of a Salesman by Arthur Miller best describes decaying cities such as Detroit and its recent bankruptcy. The story is about a negative guy named Willy Loman who refused to change his ways as society grew and changed their ways. He eventually died, broke and a miserable man. And so will you if you fail to recognize what's happening.
Get used to the change and get over it. Understand the sales opportunity it creates. And take advantage of it. If you don't, society will take advantage of you.
