Housing affordability is a nation-wide problem. Since the housing bust of 2007, little new housing stock has been added, save for oil & gas boomtowns of Texas and North Dakota. We are all now competing for limited housing in most every major metropolitan area. The solution is for every city to build more housing, not just SF. Unfortunately, new housing starts have only recovered to 1993 levels. http://www.macrotrends…

That's just a quick look of housing starts / population but we've steadily been building fewer houses and the whole thing fell of a cliff during the financial crisis. Even in the recovery, we're off the chart.
