I'd be more interested in why two such different countries as the US and China seem to have independently arrived at the same problem of ghost cities. We know that China's problems arise from a top-down, state-directed model of development under a one-party rule. But that was never the case in the US, right?
Conversely, there are very few instances of such ghost cities in India (at least that I know of). Possibly because India's urban development has up till now (though today many new cities are currently being proposed as urbanization becomes the need of the hour in India) been much more organic and bottom-up, largely because we couldn't afford otherwise.
