I guess the enforcement of the same; however, I don't wish such an 'equalizement' in the EU (viva la différence and al that). In fact, I don't wish such within a nation state either.

BTW, I wonder how the USA would look today, had there not been the big state-sponsored building of suburbia from after WWII. The programme, in part motivated by the wish to spread the population to increase the number of potential survivors of a nuclear war, in part as a measure to both settle and please returning GIs, first created the uniform living conditions that made moving much much easier, and thus also levelled cultural differences.
