1. I get that the SF market is a bit of an extreme case, but median income has not been keeping up with median housing prices in a large number of the big cities, which has then had people move away creating the same problem in secondary cities (and I don't mean that dismissively). Income has not kept pace with housing prices in LA, San Diego, Portland, Seattle, Las Vegas, Denver, New York, Boston, DC and Miami (I was going to do a long research project and link to it, but then I got lazy [call me out if you want, but this is in good faith]). This means it not just a SF problem, and given the relative population of those places, it effects a good percentage of the country. The exception is still the industrial midwest like Pittsburgh, Chicago, Detroit, Cleveland and Cincinnati.
2. My point that the bank blaming people for not saving enough to make big purchases still stands, as saving pennies to make a $10 purchase is not completely pointless, but pretty close, particularly when the income to house price gap keeps widening. What is the point of saving 5 cents if the while you save that the price goes up a dollar.
3. Going back to my original point (tangentially), we (as a country) need to come up with better metrics to evaluate the strength of the economy because the economy in the bay area is amazing right now, but it is harder to buy a house. Who is the strong economy benefiting if the median people are getting farther and farther from home ownership. I know home ownership isn't just an economic issue as local government and current land-owners are a big part of the problem, but I do believe the economy is a part of the problem and it illustrates the need for better tools to measure how well the economy helps provide people with financial stability, security, and opportunity.
