From the earliest days of the Industrial City there was a strong desire by the few who could afford it to escape its smoke and grime and even more its unlovely landscape. So with the Industrial City came the suburb. With the reconstitution of a mercantile class and the appearance of the new managerial elite, the growth of the suburbs gained greatly in momentum. Perhaps the most urgent need for improved urban existence is to accept that the modern city is, by its nature, a socialist enterprise. But this necessity is related to a yet further requirement. That is to see, far more clearly than at present, the essentially social character of the city as a whole. The suburban critique considers life beyond the city limits harmful both to family life and to the happiness and mental health of the individual. In this unpredictable world, nothing can be predicted quite so easily as the continued proliferation of suburbia.
