that and the article in question giving questionable numbers like:
>50-70k is a junior’s salary. Your people with 10 years of experience with C++ or whatever should be paid closer to 300k
50-70K out of school is normal in the US, but not necessarily all of US (70K in expensive areas like San Fransisco would be low balling, even as a new grad). 300K, even after 10 years, is not normal, not unless you started at a top company and/or have been aggressively chasing pay raises, internally or through job hopping.
BUT, while abnormal it's also not a surprising number to hear either. It depends on so many factors.
At about ~140k for one person, you will still have difficulty renting a single housing unit because you will not be able to meet % of income = rent calculations. I have experience with this (and unrelenting corporate managed rentals charging several hundred in nonrefundable application fees just to reject for low income at 6 digits..).
EDIT: It seems people took this to mean I think everybody should get maximum salary, when what I meant was you should get a fair salary. Maybe I don't understand what market rate means in the US.
