Your overall point, about limited supply / increasing demand, is not wrong. However — > For example, the number of UC campuses in California should have doubled as the population doubled. Maybe. But the number of students at UC campuses in California has doubled since 1965 — even though the number of campuses hasn’t. I think the issue is that demand has more than doubled as the population of California has doubled—because college is more of a requirement than ever.
