UCLA is 13k per year, *if* you are from California. Classes are likely impacted (even upper division) so even if a person goes to UCLA just for the last 2.5 - 3 years they could easily owe > 30k
The real cost
- rampant corruption (in california, if they ever opened the books on the non-profit entities it would be a major stunner and awakening for many people). Last I saw there was ~100 non-profits serving ~20 campuses . You can read more https://www.calstate.edu/csu-system/auxiliary-organizations/.... But what they don't tell you, those books are private and not shared with the public. Rest assured, they are money laundering machines.
- rent seekers like Pearson and Mcgraw Hill (fun fact, did you know the 2 joined forces to run a company called Follets that runs most campus bookstores (how is that allowed?)
- administration bloat
