Ann Arbor, not incidentally, appears to be doing really well relative to comparable cities and towns in the Midwest.
It's noteworthy that, beyond UofM's 50,000 students, the population of A2 is no more than 100K. That just isn't enough to draw large employers (like the Amazon HQ2) or gestate explosive growth. Thus job prospects aren't likely to boom in A2, ever, nor will A2 (or UofM) play a significant role in driving Detroit's renaissance.
I don't really see AA doing that much better than, say, Madison Wi. Which, I'm sure most would agree, is a comparable town. If anything, places like Madison and Champaign in Illinois are doing a bit better. (Well, more population growth anyway.)
