I would argue the opposite, SF is expensive in spite of the incomes (consider across the board instead of just programmers).

I'm willing to bet if you were to map the relative rate of increase of income vs. property values over time that you would see that property values are increasing at a much higher rate than income.

I earn what could be considered a good salary, there's less than zero chance in hell that I could afford property in Marin today short of winning the lottery or massive liquidity event.
