The national center for labor statistics says labor costs are about 30% of the spend [0]. STEM programs also include Liberal Arts courses, so only a fraction of the 30% goes to STEM professors pockets.

While there are a massive number of private liberal arts schools, there are relatively few private STEM schools. Most STEM degrees come from public university that are significantly cheaper than private universities.
