It's not like universities are just lining their pockets. I'm a humanities professor at a small liberal arts college with a high tuition, and we struggle to pay professors fair wages (when compared to peer institutions, which doesn't even account for differences in cost of living, and we're in an HCOL city).

I do not fully understand the economics of higher education—they're complex and often opaque—but a few things to keep in mind:

1. Tuition seems absurd, but very few students pay the sticker price. At my institution, average cost after aid is 39% of average cost before aid, and less than some of the private K-12 schools in this city. 2. "These institutions" are not a monolith. See above—especially when it comes to prestigious schools, many students aren't paying close to sticker price. 3. Families and students expect much more from colleges than they did a few decades ago, both in terms of facilities and staffing. I don't know if anyone's done a study of student wellness center staff sizes, but I wouldn't be surprised if they doubled over the past two years. 4. The sciences (and things like conservatories) are particularly expensive because of equipment/lab costs. Someone has to pay for all this. I think more should come from the corporate America (not sure how), which benefits greatly from these programs, but I'd venture to guess most comes from tuition and government grants.
