I lived in SF, then moved to Athens, GA for 6 years, then back to SF. I have a lot more disposable income in SF because while my rent doubled, my salary tripled. On top of that, anything with an MSRP set at a national level (cars, bicycles, guitars) is a much, much smaller percentage of my monthly income. On top of that, I can contribute 3x as much to my retirement as I did before. It's win/win/win.
