Saying cities are what defines civilization from primitive cultures, Hayek looks at the role of government and society in defining city life. He argues that while private property rights are not the end-all decider of what one can do with land, the marketplace has been the most efficient allocator of resources--as opposed to central planning. He is harshly critical of rent control and housing cost ceilings. He also looks at government subsidized housing. He finished analyzing building regulations.
