My employer pays me less because of that, and you know what? I'm okay with that. My discretionary income after housing and basic living expenses are removed is way higher than that of someone in a HCOL area.
I have a 3300 sqft house that was built in the last 10 years and a quarter acre of land. That costs me $1400/month. If I wanted a comparable standard of living in SF, the wage gap between here and there would need to be many thousands more that it really is.
So pay me 20-25% less, it makes me more employable and I have a better standard of living than you do.
