Big = American.
Big cars, big business, big government, big problems, big (attempted) solutions, big, big, big.
Tackling the idea of growth and bigness way back in 1980 (sense of scale: Donna Summer, Kenny Rodgers and Pink Floyd were the chart toppers), Sale takes the long view of human history and does an admirable job of tying some of our most vexing problems not to misguided policy, greed, or any other common scapegoat, but just to sheer size.
As Gladwell and others have recently noted, humans seem to work and cooperate best when group size remains within a given range. Sale applied this concept not just to governance -- although that figures centrally in many of the chapters -- but also to energy, transportation, agriculture, civic involvement, education, urban planning, environmental preservation, etc., etc., etc., etc. And etc. Really, this is 500+ pages of Sale pounding on the virtues of going small and local (Question, Mr. Sale: is 560 pages too big?). As impressive as the tome is, the real flash of genius is that he was a couple decades ahead of everyone else on this particular front.
The good news? Sale pegs the upper limit for population of a functional city at about 200,000. Welcome to Spokane.
