Last night's installment of the Summer Documentary Series on Michigan Radio was on "The Sprawling of America", produced by the Great Lakes Radio Consortium's The Environment Report. I was glad to see them focus on the topic, until they unquestioningly repeated the fallacy that density - revitalizing city centers and urban neighborhoods - is a violation of property rights. The popular idea that sprawl is the product of a free market, "What People Want", is probably the single biggest mistake preventing us from either effectively addressing sprawl or effectively revitalizing our cities.
