People in the US don't do well at saving. But SF is still abnormal -- you need a considerably higher salary to have the same quality of living + savings in SF

People in the US don't do well at saving. But SF is still abnormal -- you need a considerably higher salary to have the same quality of living + savings in SF as compared to many other cities. For example: elsewhere in this thread it was stated that a one bedroom apartment runs $2500+ in SF. In my neighborhood, a decent one bedroom apartment might run $700. Sure, you might earn $90k instead of $100k, but you save twice the difference just in rent.
