It’s too late for Detroit, but what if the city had its own currency?
When your key industry and most of your population wander off, you are
going to get money trouble, but having to go bankrupt merely to force
your lenders to accept their fair share of the pain is crazy. Instead,
denominate your payments in Detroit Dollars. As Detroit crashes, the
Detroit Dollar crashes along with it and everyone suffers equally with
no complicated legal mechanism required. Or if the city booms, everyone
benefits.
You vote in your own town, right?
