It is not often a primary factor largely because it is hard to know in advance. Also because of the above. Given a choice between salary and other things, people choose salary. However, the "choice" is made in other ways. People stay in or leave jobs or even industries for non salary factors. Perks, culture, coworkers, pressure, interest in work etc. While it may be hard to find cases that people choose a job because of good co workers, it's probably easy to find cases where people leave for the reverse reason.
