I agree with the sentiment that the density/walkability debate is being falsely construed as a battle between 30-story condo towers or five-acre estates. Perhaps this is because the areas that are considered most livable by the affluent or to have the most potential are the exurbs and the dense urban core. The map in this article http://www.urbanophile.com/2013/05/15/chicago-the-daley-deals-by-robert-munson/ is revealing: it shows that the neighborhoods in the \”bungalow belt\” of Chicago (which offer a good mix of home ownership and walkability) have seen the largest decrease in per capita income in the past few years. Hopefully, the Great Congealing will involve a greater level of investment in existing middle density areas as well as the creation of new middle density areas.
