The question of gentrification The question of gentrification is made complex by the fact that the urban qualities it produces—lively street life, profuse commerce, preservation and upgrading of old buildings—are highly desirable, the substrate of urbanity. The problem with gentrification is with its particulars and with its effects. Gentrification suppresses reciprocity by its narrowed scripting of formal and social behavior, by turning neighborhoods into Disneylands or Colonial Williamsburgs, where residents become cast members and the rituals of everyday life become spectacle or food for consumption.

The plan must anticipate all that is needed Ebenezer Howard set spinning powerful and city-destroying ideas: He conceived that the way to deal with the city’s functions was to sort and sift out of the whole certain simple uses, and to arrange each of these in relative self-containment. And he conceived of good planning as a series of static acts; in each case the plan must anticipate all that is needed and be protected, after it is built, against any but the most minor subsequent changes.
