Earlier quoted context omitted.
We had a dev working for the summer who got a job at an SF startup this past week. He's making $2k a week, but his rent for his apartment costs $3k and he's got roommates. As someone who has lived off of $40k and rented a $1.4k a month loft that was absolutely palatial, in the middle of the city with great views, this sounds like insanity. My coworker who is from the Boston area was similarly aghast at the difference…
FYI, you don't need to pay $3k - I lived in the Mission / Potrero Hill area (with roommates, mind you) for a few years, and my rent had always been between $1000-1850/mo. Centrally located, safe(-ish), and beautiful. You can run through Bernal Heights Park, get ice cream at Humphrey Slocombe, and bike to the 24 Hour Fitness on 16th and Potrero. If you're in tech, you can definitely live well in SF :)
