Please include stock grants, because otherwise it's a silly comparison. With that included, I know a lot of people in SV, NYC, and even Pittsburgh who meet that bar. Google, Facebook, Dropbox, Microsoft -- all of these places pay over $200k total compensation for senior engineers. A grant of shares of GOOG or MSFT every year isn't likely to completely disappear within the vesting period...
Stock grants for non-executive employees are rather rare (at least on the East Coast).
And even then, once the bubble pops, if you don't sell (there is usually a vesting period), they could be worth much, much less than today. Remember 2000-2001?
I'm confused about this "east coast" thing. Many of the major tech companies that compensate in cash+RSUs operate on the east coast at some scale or another. Heck, in Pittsburgh alone, you can pick from Uber, Google, Facebook (Oculus), and Apple, of the "really big tech companies that give their employees RSUs". You'll find similar options, no pun intended, in NYC and Boston, at minimum.
As I said: The rolling vesting offered by most companies means that you're selling stock every year after your first. So if you ignore the first year (or pretend that it's poorly compensated), it's not that shockingly bad.
