I was working retail in Eugene, Oregon during the 2014 University of Oregon grad student strike. I had a little bit of a chip on my shoulder because I was working retail with a master's degree in physics (because I did not have the endurance to complete a PhD, but had not yet accepted that fact).
My then-partner was part of the strike. One of the strike demands was higher wages as teaching assistants. And while I worked 40 hours a week, for $11/hr, I made considerably more and worked fewer hours than her. She put in probably 30 hours a week just on her teaching load, plus an additional 30 hours split between explicit course work and dissertation work.
It's crazy that a job that requires excellent marks while completing a 4-year degree pays worse, has worse working conditions, and is considerably more competitive to get into than a job selling office supplies.
One of the other things the grad students were demanding (which they only sort of got) was paid parental leave, because they did not fail to notice that most of their professors were in their late 30s or early 40s before they could afford to stop work long enough to start a family. It was very rare for two academics to have children together, because of the heinous, career ending financial cost to having children when you were young enough that their high school graduation date was before your expected mortality.
