This is unsympathetically referred to as "ruin porn" around Detroit. Yes, there are an exceptional amount of abandoned buildings (there are about 600,000 people in a city that could probably comfortably hold 3x that), but there are also world class universities, sports arenas, restaurants concert venues, houses and apartments, etc. http://www.viceland.com/int/v16n8/htdocs/something-something...
I assume when you mention world class universities you're referring to UM Ann Arbor -- maybe Kettering too. Is there a lot of cross fertilization between the city and the schools? Do a lot of UM students live or move to Detroit?
