I regularly get calls from reporters asking about Tenderloin “gentrification.” When I recently asked one what they meant, they said that they saw that Mikkeller Bar had opened at 34 Mason Street. I asked how the opening of a bar in a long vacant restaurant space constituted “gentrification” and he replied, “It doesn't. You’re right.” But this reporter was not alone in extending “gentrification” beyond its traditional usage as a process by which low-income, working and middle-class tenants are replaced by more affluent tenants/owners. Our friends at the National Housing Institute recently held an illuminating conversation among urban activists, “Inside Gentrification: The Emotional, Physical, and Financial Implications.” You can read the illuminating discussion by clicking on the link.
