The only solution to displacement is building more housing. Davidson at least acknowledges this, but only in the penultimate paragraph of the response to criticism of his original piece. This is after his advocacy of worthless affordability preservation programs and various harebrained ideas about permanently limiting rents. The way to accomodate gentrification is to build more. If prices are universally low, the wealthy won’t be driven into poorer neighborhoods – and if they come, only benefits will accrue to the original residents. The rest, simply, is worthless.
