Affluence is likely to remain in developed cities—whose long establishment, high productivity, and richer incomes tower over developing cities. The latter have to catch up in productivity (and underlying areas like open governance, lack of corruption, and stronger physical and social infrastructure), even while growing spectacularly in population and employment.

If those improvements occur, employment patterns could change dramatically—cutting labor dependency and jobs in developing cities. But that issue may be upon us already as employment struggles to regain pre-recession levels and as a new phase may be dawning in the information revolution where less work is required and wealth must be shared in a more rational manner among the soon-to-be 9 billion of us.
Meantime, our cities are intertwined. As long as the West possesses the time and money to buy goods and the rest of the world has the labor to create the products, symbiosis will continue, each side needing the other to prosper and making the case at least as strong for intelligent urban collaboration as it is for competition.
