Done.
But:
1) Job and life satisfaction are way more complex than anything your questions can isolate (Measuring happiness and its causes is its own field of study within sociology.)
2) You're completely ignoring people on their second or third careers (I've got an MA, but it's not in a computer-related field)
3) You've selected an industry/field (IT) where there are still a LOT of folks (especially older guys left over from the '90s dotcom bubble) with relatively little classroom training or few relevant academic credentials, and the workforce as a whole holds a much wider variety of contradictory opinions about the relative merit/value of credentials, compared to other fields. IT guys tend to run the gamut from "screw your book lernin' and grab a soldering iron" to cert-whores and MIS/MBA process weenies. I suspect you would find most other "skills economy" workers with similar compensation packages (civil and mechanical engineers, doctors, lawyers, etc.) much more likely to embrace a formalized X-years-of-college-and-state-exams path to a career.
Anyway, good luck with your final project.
