York was, London is, and Edinburgh will be the biggest of the three. The City has not just grown bigger than its boundaries, it has outgrown the concept and vocabulary of the city itself. The distinction, at least in this country, has been blotted out between agricultural and urban life; television, the automobile, and the agricultural revolution have taken care of that. Detroit must diversify its industrial and commercial base if it is to escape the situation in which we now find ourselves. Every time, as the saying goes, the automobile industry catches a cold, Detroit catches pneumonia. Downtown is an anchor and a radiator. Literally everything radiates. And if we have a rotten center, then we have a rotting city. A city is like an apartment house. If it is filled, there should be no effort to bring in any more people. The concept that "there's room for one more" just doesn't apply.
