Depends on the population you’re asking about. The postdocs are generally there to pursue a faculty position or to broaden their skillset and springboard to the next thing. 65k seems high for a postdoc in most fields though. My academic postdoc salary a few years ago was 50k, and that was considered generous. Staff, research scientists, lab techs, and other non-postdoc, non-faculty technical roles in academia are not generally in the career path to a tenured position, so I’d guess environment/work would be primary motivators.
