Actually, I think you have to go back further. My grandfather, a poor kid from west LA, went to UCLA and then UC Berkeley as an engineering student back in the late 1930s / early 1940s.
He learned Latin in high school (think inner city kid learning Latin). Grew up with all the airfields in LA and mechanical engineering seemed like the thing, I guess. So despite being interned (he was a Japanese American) he went on to be a very successful engineer and eventually businessman (owned his own hydraulics company, etc.).
It's arguable that a lot of this happened because of a golden age in California's educational system. Same thing with my parents. I've met them and they're idiots -- but at least my father benefited greatly from UC Berkeley (he's a philosophy professor).
I think PG is right to question what exactly is going on. But there really was an extraordinary investment in higher education (for whatever reason) in the early- to mid- 20th century. And arguably, that affected a lot of things which we Californians take for granted.
I think what the OP is trying to say is that our attitude about public education has changed. It was irrational, the level of investment that was made into higher education pre-1980s (both raising and allocating funds). And today's set of challenges may require a different emphasis (e.g., charter schools, leaner campuses, more online learning, etc.) -- but that generous spirit that, afaik, built California into a great state -- that's not worth overlooking.
