I had worked at a natural foods co-op for a few years between undergrad and grad school, and although my marketing role paid more than some floor jobs, I was blown away when I started as a teaching assistant and made essentially the same wage. I could make the same money grading papers as I had in the real world? No way! Then I entered the private sector again where my starting wage was twice what I made in academia. And I thought I was rich. Until a few years later when I was making multiples of my former hourly rate.
Lots of folks in these roles have no idea what their time is worth. I kick myself for being so naïve at the time.
