Do you have a source of this data? I have tons of friends in the Bay Area who work at a wide variety of tech companies, and none of them are making $100k or less. I guess maybe they really are "all above average" but I find it hard to believe that the median salary for software engineers in the bay area is really $100k.

Sure. [1] [2]

Of course, this is just "a couple minutes of google research"--I am not a subject matter expert, as someone on HN kindly pointed out last time I posted these here. Also, they are based on self-reported surveys and don't include sellable equity, so take it with a grain of salt. I don't know where better data would be published. I'm intuitively not too surprised by these figures--I think the HN demographic is probably pretty skewed towards the higher end, judging by all those threads where people toss around $150K and $200K salaries as "normal".
