The income and standard of living for software engineers in Silicon Valley is so high that low wages are not the constraining factor in engineer population.
None of them has yet taken me seriously, but thankfully this reduced the number of calls I was getting.
I wish more people were like you.
Disclaimer: I do the same.

The median price for a 3br house in SF is (I used zillow's numbers for this) 1.1Mil.
(btw, check the pay for the other "top 10" professions in high cost areas like SF. It does make economic sense for top students with good options to choose other fields).
