You didn't say "cost of tuition" in your original comment.

Further, I think it's disingenuous to only consider tuition. Cost of living in e.g. Berkeley is ridiculous, literally more than tuition. [1]

(I understand that living is not something Berkeley can fix, but it's very much their problem and a concern on students' minds, regardless of whose "fault" it is)

To only consider tuition is a cost-shifting marketing tactic that these schools use so you don't focus on the bottom line. Their goal is to get you to attend. Period.

Let's look at a less prestigious school-- UCSB tuition is about 12k, but total cost might be 24k (official estimate says 32k [2], but I have the random fees they have to not be applicable, e.g. "campus fees" or "books")
