I would agree, going the other way.
Before university, all I knew of rich folks was that they poached the good teachers from my high school (we were a magnet school in the poorer inner city, back when cities were poor). Lets just say that I found that there was more nuance to all those kids from suburbia.
I went into university steadfastly believing the roster sheet of progressive policies. Then there was economics class, and the in-depth conversations around that, and I came to realize that a lot of policies are double-edged swords, either difficult to implement correctly, or just outright too good to be true. For example, you can't really elide the fact that prices provide important signaling to the markets, that in turn influence supply and demand.
That having been said, I don't think the libertarian wing nuts I'd met came to the same sort reckoning,... they still seemed to think the free markets are magic pills... so I figure that I learned more from the experience than they did.
University was a confusing time. There were a lot of folks who were a lot more privileged than me, who were smarter than me, but not very motivated. It would take many years after college before it became clear how things even out. (They are still on good footing thanks to their privilege, and they're not bad people. I have sometimes enjoyed seeing them again – when I do – like it was old days. I don't envy them anymore. And I wouldn't switch places either.)
Life is complicated. University forces a kind of mixing – and a certain kind of critical thinking – that forces you to look at how complicated it is. Sometimes, things just are.
I've been to the other end of the spectrum, been around lots of people who never went to school or who dropped out. Or who had it easy in university. I interact with folks who never had to pick up that kind of critical thinking. It eventually becomes plain and clear the kind of subtle difference it makes in people's lives over time, and across generations.
It is in life as it is in board games. Randomness and complexity obscure the "winning" strategies.
