Are you suggesting that an industry driving people into cities is new? It isn't. It goes all the way back to the industrial revolution, and the main alternative before us at present (suburban living) only dates back to the '50s. And it's not a panacea: the car-oriented nature of suburban life is environmentally pretty terrible (not to mention that detached single-family dwellings are less efficient to climate control, and more expensive to provide services to for municipalities). And suburban life brings with it the long commute, the length of which is a better predictor of happiness (negatively, of course) than almost any other demographic factor, including income, marital status, house size, or any of the other things people think make their hour and change in a car every day worth it.
