There isn't much inner city left in Indiana. There's that part in the northwest near Chicago where the abandoned steel mills, strip clubs, and casinos are, and then there's the more economically disadvantaged parts of Indianapolis. The problem is as much middle of nowhere as it is inner city. Indiana's social safety nets are more dysfunctional than any other state I've ever lived in, and the middle of nowhere parts have no infrastructure, no jobs, no nothing.
This article doesn't surprise me in the least. When I was in college in Indiana, I knew a lot of people from the more well-off Indianapolis suburbs, but practically none from inner-city Indianapolis, and only a smattering from the middle of nowhere in Indiana. There's a good reason for this. If you're not from the more well-off suburbs, you are pretty much screwed.
Indiana was a depressing place, and I'm glad I left. I just hope Pence doesn't turn this entire country into Indiana.
