Michael Lewyn, writing to the New-Urbanism mailing list: "Almost any walkable neighborhood was available to the average middle class American in 1953. Today, most such areas either (1) are off limits becuase they have been turned into (a) ghettoes or (b) marginal neighborhoods appealing to hipsters and singles but not to families OR (2) cost a zillion dollars (e.g. Upper East Side of NYC). Today, most Americans (especially families or people whose jobs are in suburbs) pretty much are stuck with CSD [conventional suburban development]."
