I'm going to use your example of Detroit as my example here. One of the problems with getting people to move into less desirable cities like Detroit is that the less desirable areas are pretty nasty with poor resources, dirty streets and sidewalks, etc. Infrastructure is a joke in many of these neighborhoods, and the city government is still too obsessed with just particular areas for growth because that's where the tax money is. If someone would come up with a way to not just get people to come into the neighborhoods, but to actually clean them up and get city and state government on their side, that would be the real winner.
