The reality is that the number of people making over $200k is just not that many. Very senior people and directors of certain departments, sure. And you've got some $250k+ VIPs out there. Some.
For everyone else, even those in the Bay Area, it caps around $180k, or $10k/mo after tax. Stay for long enough and you might get a nice chunk of change you can put towards retirement, assuming that the stock is still flying high at the time you can actually do something with it.
The $250k engineer is a myth. By the time you are making $250k you aren't writing code anymore. In fact, you may have never written code in your life. You're a director, VP or C-level executive of an engineering department.
