Suburbia as Ponzi scheme. We have subsidized suburban growth through debt and taxes, and reaped the short-term financial rewards of that growth, but at the expense of taking on ever larger long-term liabilities in terms of infrastructure maintenance and a very energy intensive transportation system. I disagree with Strong Towns on the appropriate overall scale of habitation (more people and a much larger fraction of our overall economy live in cities, not towns), but this is (another) good critique of the American Nightmare.
