So while it's very likely that the cost of housing will increase in this situation, again I think people will still be better off overall. People will have increased purchasing power for non-housing goods and still pay the same percentage of their income for housing, even if that is now a percentage of a larger number.
No, its not. Real estate -- including housing -- is very much driven by value, and for most real estate -- and definitely housing -- and key component of value is location.
> That's why in SF it seems that housing prices rise in lock step with wages in the dominant industry (tech).
Convenience to work of a given pay is a key component of the value of housing; its not priced according to what the buyer can pay, its priced according to value, and the buyers are the ones who can pay that value.
Anything that isn't provided by a freely competitive market can be like this in the long term, and anything where the supply side can't quickly respond to demand-side changes can be like it in the short term.
