Brutal winters and high crime rate, what else? Of course, there's lots of other problems like decrepit infrastructure (like the water pipes in Flint nearby), and I seriously doubt there's any kind of nice downtown area to walk around in like in nicer cities. I hear the suburbs are OK, but that doesn't exactly make me want to live someplace.

Basically, AFAICT, Detroit sounds like someplace that would be OK if all you wanted was to live in the suburbs and never leave your house, and you have zero interest in outdoor activities, and don't care about going to nice restaurants downtown. The crime downtown is terrible, there's huge stretches of abandoned neighborhoods, the winters are horribly cold; I honestly don't know why anyone would want to live there. The location surely made sense a century ago back when shipping on the Great Lakes was a big thing and the location was sensible for manufacturing and shipping reasons, but those reasons are all gone now.
