Total comp in Bay Area is often around $300-400K. That includes generous equity though, so may not be relevant when talking about startup salary affordability.
For FAANG I'm pretty sure it's in the $300-400K range. If you include all tech jobs (including startups and old-line jobs at eg. IBM, HP, Oracle, National Semiconductor, etc.) I could see it averaging out to $150-200K, but only because the previous-generation companies don't give equity and equity in many startups is worthless. The flip side of this is that if you pick the right startup (AirBnB, Lyft, Uber, Stripe, etc. when they were startups), your equity is worth millions.
