Due to unprecedented urbanisation you effectively have runaway inflation in large cities, which is wiping out whole economic classes. Raising interest rates would be the only sane thing to do from the city perspective, but outside of the cities high interest rates would wreak havoc to the small amount of industry and jobs that remain there. I don't think any country has come up with a solution to the economic imbalance created by the flight of capital to cities.
