alt Hacker NewsThere are so many confounding factors that this can't be taken at face value. Immigrants go where jobs are in general and it's demand for workers that causes housing prices to go up. If there was zero immigration there would still be huge housing demand in SF and LA.
You think that a minimum of 35% of demand being artificial isn't a factor that can be seen to increase overall demand?
edit: I say "minimum 35%" because that is just the percentage of immigrant-demand that managed to secure housing. Hard to say exactly how many more immigrants are bidding on SF & LA-County housing but 35% is the absolute floor.
