The question is, once the company has decided it wants you, what’s that going to take? Making national median offers to Bay Area candidates essentially swears off of ever hiring them. That could be a choice, but for now it remains a bench of talent and experience that companies want to draw from, even if not exclusively.
Making Bay Area offers to rural candidates is giving them 4-5x their next best option, which is characteristic of either a) the devil, or b) rich people making expressive displays rather than business transactions.
It’s like everything else, your leverage is your next best alternative, and until work goes fully remote location is a factor in that.
EDIT: I will add that if you think calibrating an offer based on the worker’s alternatives is crass, think for a second about what exactly your skills, education, and experience are for. Those work through the same mechanism. If that mechanism is wrong, you should be happy to work for the national median wage across all industries and all education levels. Even a mediocre SWE salary is way too high.
