Indeed- I thank the FANGs everyday for pulling up my salary. In 2013 I was making about 1/3 what I am now in the financial industry in NYC doing algo trading/HFT. I was reluctant, but after years of seeming to miss out on the big money that everyone talked about finance people making, I finally just decided to look outside the industry. I got a remote job with a company in the valley, and got a 60% increase in comp, that after 3 years grew to just a hair shy of 100%. I was pretty much the first defector to leave finance for tech in my circles, but more followed. I jumped around one more time, with a financial company who truly pays top tier salaries (to match tech companies), and am now making a full 3x what I was just a bit over 5.5 years ago, with a much better work life balance and general work environment.

I can't imagine this would have happened without Goog/FB/Apple/Netfix, etc. Every day I reap the benefits of their competition for talent without having worked at any of them.
