It’s only big deal in the USA because outside FAANG, technology really doesn’t pay that well. There are a few other companies, but your income is capped elsewhere
Finance doesn't pay nearly as well as FAANG does. They used to, pre 2008, especially with enormous bonuses, but that is a thing of the past. Maybe with the exception of Goldman Sachs, the other banks rather pay market rates or even below.
Non-FAANG companies that I personally know pay senior engineers more than 400 k$/yr in TC: AirBnB, Slack, Square, Uber, Lyft, Dropbox, Twitter, Pinterest, Spotify.
(This isn't to name the even longer list of private companies that have comparable comp with reasonable assessment of their equity)
