The collectivist left hates the suburbs, where private property and automobiles give power and freedom to the individual.
Self-driving automobiles will soon enable the middle class to live farther from the dirty noisy city work hubs, and families will jump at the chance. And safe/reliable self-flying small airplanes will be available soon after that, enabling double that distance. American big cities are draining out of Americans, and only treading water population-wise because of a constant stream of third world imports, desperately needed to keep the city government worker pension plans from going bankrupt.
