I just don't see Detroit getting anywhere near as bad as New York. The population density just isn't there - half of Detroit is vacant land at this point with around half a million people. New York had nowhere to build, so instead of out, they went up.
The problem with Detroit is there are many people that are not incredibly intelligent. There is a large part of the area that is low income and just plain very reliant on the government for everything they do. So, in that vein, probably not much different than parts of NY.
