For the past 60 or 70 years, government at all levels has made suburban life easy and urban life hard: by building highways to facilitate suburban commuting, by insuring mortgages in suburbs but not in cities, and by moving urban schoolchildren around in the name of racial balance while tolerating overwhelmingly-white suburban public schools.
