...Americans didn’t stick to cities, which makes us different from the people in other industrialized countries. We no sooner arrived in town, turning those towns into great mid-century metropolises, than we decided to take off for the green world beyond, so that by the 1970 Census, we had become the first suburban nation in the history of the world. And Detroit led the way, with a population curve up and down just like everywhere else, but with its urban decline a lot steeper over the past sixty years—so typical a place that it only looks like an exception.
