My gut ( after lots of reading, viewing and connecting the dots ) tells me that there are 100's if not 1000's of small/mid-size cities like Cleveland that are really not needed anymore. There has been little to no real economic growth in many of them for a long time. Many of them barely get by with the number of low paying jobs created and most likely survive through government incentives and various tax schemes to build anything. I may be wrong. But ask yourself "why live in Cleveland or Detroit or Gainesville or Buffalo or Allentown or the many others like them).
You could say all the same things about most of rural America (minus the graft part, of course). Manufacturing jobs left rural America years ago and nothing yet has filled the vacuum, nor does there appear to be anything on the horizon. Not to minimize the issues, but I still believe small/mid-sized cities are far better positioned to handle this than most of rural America. As long as an area has good universities and infrastructure, there is a shot at re-tooling into a modern economy. IMO Cleveland falls into this category.
I visit Cleveland quite often as my company has a remote branch there. It's not quite the cesspool in decline that the OP's stats make it out to be. It's rebounded quite nicely since the most recent economic depression.
I've actually been looking at Cleveland a little harder for investment because Columbus has gotten so expensive. Many of the C-class neighborhoods are actually in better shape than Columbus, which has some large patches of internal rot that never seems to improve. Columbus multi-fam housing stock is highly fractured between expensive wealthy suburbs/trendy gentrification areas and urban decay, with very little in between. In Cleveland, there appears to be way more B/C-class stock there at lower prices. The costs are higher due to the fact that you can't pass the water bill to the tenants, and taxes can be high in spots (though the same can be said for Columbus).
Biggest downside to Cleveland IMO is the weather, but almost everyone except the most hardcore deniers are starting to face the fact that climate is getting warmer, which will over the course of the next several decades make northern states more desirable. Climate in Columbus is far warmer than it was when I was a kid over 40 years ago, when it was common to have winters containing extended periods of sub-zero temperatures. Sub-zero temperatures are almost anomalies now. Cleveland's by a great lake, so it does have a climate that is somewhat worse than Columbus, but I've heard a couple times recently that Grand Rapids, MI is booming, and I'm not sure anyone has worse winter weather outside of Siberia or Antarctica.
