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.
I disagree with most financial aid and admissions offices, who seem to regard loans as "aid"
Please dig deeper if you care about this issue. My wife works at a state school and by far the overwhelming factor on rising tuition has been the systematic defunding of state schools since the 1980's. Our state university currently receives about 20% of what it once did from the state 40 years ago.
Imagine if the school was just a building with rooms for teachers to meet with students and labs to do research in. Maybe it wouldn’t be fun for the sporty people and their name wouldn’t be in a cheerleader chant but it would be very focused and efficient
Studying at an American campus is like buying an expensive timeshare.
