> Compensation isn't nearly as elastic as housing prices though.Because there is usually room to give. If people were on the brink of actually having to leave due to rising costs, incomes would lose their inelasticity pretty quickly, insofar as the need for labour is required. There is always superfluous work that is useful at a low price, but fine to give up completely if costs grow too high.
> Not only that, the demand side for housing is also the supply side for the job market, so prices are squeezed on both sides.
Squeezing is necessary to a point. After all, the economy eventually seeks equilibrium. It has been the case – at least before housing costs grew out of control – that one could make a fortune by moving to the Bay Area, where average incomes are significantly higher than most of the rest of the country. Now the costs are rising to close the gap with lower-income areas.
If someone in a low-cost area has a gross income of $30,000, and expenses of $25,000, then someone in a high-cost area with a gross income of $150,000 can take on expenses of $145,000 without being any worse off. While housing isn't the only cost one has, it is usually among the largest (with taxes being the other major expense). Having $145k to spend on expenses each year can go a long way.
