You're setting the bar for hiring faculty members far too high. Perhaps you mean tenured CS faculty? (Source: Stanford faculty in the process of moving to Google Research)
Brand-new CS assistant professor hires at any research-intensive CS department (there are ~80 of these schools in the U.S.) probably come in around $100k right now (as arjun said, many salaries are public) ... now that's a 9-month salary, so if you get grants to fund your summers (which you will if you're in the groove), that's a starting of $133k annual. That's not bad, considering most of these schools are located in low-ish cost of living areas. Of course, there are no stock options, huge bonuses, and other lavish benefits of industry, but it's definitely still a financially privileged position.
I meant that the parent's analysis in his footnote of what the minimum position and starting salary would be for a faculty member to ever move is setting the bar too high; it seems my wording was vague. His academic numbers seem spot on, but I question footnote [3].
What would you expect appropriate bands to be, then? For tenured/non-tenured faculty?
Given that most academics have, almost by definition, previously prioritized their work environment over their salary, one shouldn't even assume that an academic receives an (immediate) multiple factor raise by making the transition.
