Are you kidding me? Half the faculty at any college, no matter the price, are adjuncts, who earn $2500 or so PER CLASS PER SEMESTER, while the 30 students in that class are charged $2500 EACH for that class. It's as close as you can get to free labor for knowledge work, basically the original Gig economy; Uber for teaching.
That adjunct pay seems low but not unheard of. Here is a thread I found on it [1]. The cost per student per class is not far off (at least at my state school). Assuming a 3-credit undergrad class at Penn State @$800 ($2400) [2].
