Intel has grading system which you can try to google. You are paid according to your grade (+ benefits based on performance, etc.) Also, you are evaluated against your grade and you can gain or loose a grade based on performance (but more likely than loosing a grade is that you will be let go).
I have been given a grade that was over my head at the time and would require me to technically advise and coordinate multiple projects, have outside presence (ie present at tech conferences, take part in opensource projects, etc.) and basically work at a level that I have not been ready for. And yet I was not able to make ends meet.
I guess when I was hired I got absolutely excited about what I am going to work on and plans for bright future, that I have completely ignored the possibility that I may be over my head and that I may not be able to advance so quickly.
Your one company gentrifies the hell out of some things, not everything, and ultimately all fates are tied to their fortunes. They do a layoff, hiring freeze or even a salary squeeze and eight months later a few restaurants and one of your favorite stores shut down. You find out they've been late on payments to people and vendors for the past 6 months.
I recall the first time I heard someone interviewing at Intel and I asked why they were, 'in the middle of nowhere in Oregon' and nobody had a good answer to that.
What I've learned about manufacturing since then makes me think, "lax environmental rules and watchdogs".
Also, I imagine Intel would gain very little from being located in, for example, the Bay Area or NYC. It isn't like they are some little startup that needs to go out to bars to find new developers or whatever.
