I'm shocked by some of these answers. Is SF that ridiculously expensive these days? For reference, I was saving 50% of take-home on a $90k salary three years ago, living without roommates in a nice neighborhood in NYC - which isn't exactly known for being inexpensive. What do you spend that much money on?
