“If we are serious about moving toward a saner housing future, the options in terms of federal policy are relatively clear: we can prevent land from being subject to market forces, either through government ownership of land (housing projects) or through heavy regulation (rent or land-price control), or we can prevent the ever-increasing value of land from displacing people (programs such as Section 8 vouchers would fall in this category of solution). Instead, we do almost nothing and hope the market works it out. Without major new regulations, we can expect what's happening in San Francisco to continue in virtually all major US cities. In the same way that the suburbs were once inaccessible to the poor, in the near future American cities will become gilded jewel boxes, and the exodus of the poor to the suburbs will continue unchecked - that is, until the rent gaps in cities become too small to make gentrification profitable, and a new form of spatial filtering begins.”
