Those number are way off for the greater Seattle area. $70k is what university students make their first year if they interview well and have had an internship/summer job before graduating. You factor in contracting rates for folks with 10+ years experience and principle salaries at Microsoft, Amazon and local Google/Facebook expansion offices and you start moving strongly into the $200k/year + stock & benefits neighborhood (assuming you can stomach the political bullshit, that is...).
