The absolute top of the senior ladder lists $200k. At one single company, for one job. (And checking the same thing for Mountain View doesn't yield a significant difference)
So I don't think $110k is "half the going rate" :)
You can also look at aggregate U.S. household income statistics. Only 3% of households make $200k+ in total income, even after you count both incomes for married couples, and including investments/bonuses. And, most of those aren't in tech. So you'd have to have a very particular social circle for it to be anywhere near normal for even senior people to make $200k+. Just by aggregate numbers, low 6 figures is fairly common (16% above $100k), but things drop off rapidly above that (6% above $150k, 3% above $200k, 1% above $300k).
I _am_ a sr. dev., and I'm fairly certain I'm not making $200k.
But let's assume I'm not as senior as I like to think I am, and check glassdoor.com instead: http://www.glassdoor.com/Salaries/los-angeles-senior-softwar...
