To really invigorate places like Cleveland, you might need a combination of high regional population growth, limits on sprawl, AND a lot of good work by the city and its organizations. This might be possible as the South gets warmer, even with the half-back scenario taking much of the returners.

That seems possible in the coming few decades, with a gradual ramping up. The good news is that a little momentum can help sustain itself and create bigger momentum. Limiting outward sprawl might be tough in region that's already a patchwork of towns and other sprawl.
