"America finds itself nearing the end of the cheap-oil age having invested its national wealth in a living arrangement—suburban sprawl—that has no future. When media commentators cast about struggling to explain what has happened in our country economically, they uniformly overlook the colossal misinvestment that suburbia represents—a prodigious, unparalleled misallocation of resources. This is quite apart from its social, spiritual, and ecological deficiencies as an everyday environment. We constructed an armature for daily living that simply won’t work without liberal supplies of cheap oil, and very soon we will be without both the oil needed to run it and the wealth needed to replace it. Nor are we likely to come up with a miraculous energy replacement for oil that will allow us to run all this everyday infrastructure even remotely the same way. In any case, the tragic truth is that much of suburbia is unreformable. It does not lend itself to being retrofitted into the... mixed-use, smaller-scaled, more fine-grained walkable environments we will need to carry on daily life in the coming age of... reduced motoring. [...] Instead, this suburban real estate... will enter a phase of rapid and cruel devaluation. Many of the suburban subdivisions will become the slums of the future. […] The seasons… will continue with the great cycles of contraction and expansion, and at some point, in the future, who knows how many years distant, some of these cities in a land once called [the [[United States|United States of Northern] America]] may be robust and cosmopolitan in ways that we can’t imagine now, any more than a Roman of A.D. 38 might have been able to imagine the future London of the Beatles."
