Not OP, but here's a possibility: In the last month I've spoken with numerous people who earn $200k/yr. I'm not sure I've spoken with someone who earns Khan's salary in the last year. (There is one guy who probably earns that in good years, but I'm not sure the last year has been a "good" one.) That is, regardless of whatever rarefied Silicon Valley filter bubble we're pretending exists here on HN, Khan is not raising money from Silicon Valley. He is raising it from the world, and a very low percentage of humans earn $800k/yr. Granted, however, this is not just a problem with Khan Academy. Many "non-profits" pay their executives unreasonable salaries.
