Joel Kotkin: "Generally I find cities interested in either low-income or luxury housing. This is my critique of what's happening in downtown L.A. In some cases, developers have to build high-end because if you're going to subsidize low-income, the only way it cancels out is to attract the high-end that will carry everybody else. But the real issue is, Can we create middle-class housing? It would be wonderful if people at regular jobs in downtown L.A. could afford to own a condo and walk to work. That would do more for the city." This is absolutely right on the money. I see it at work in Berkeley on a daily basis, and it seems to me to be inexorably making the city a hostile place for the middle class. Restrictive or gun-shy approaches to dense infill housing around many cities like Berkeley are the main culprit.
