Let's not leave out think-tanks and orgs like the WEF that seem to exist only to launder the opinions of billionaires. And mainstream news publications like the New York Times: https://en.wikipedia.org/wiki/Friedman_doctrine
While I don't disagree with many of your points, we shouldn't kid ourselves that we live in the best of all possible worlds for most working or middle class people.
Yet theres a difference between hitching a horse to a wagon to move things vs joining a bestiality cult that worships horses.
A university is hardly the only place for terrible ideas to thrive, just look at silicon valley culture and this orange site.
Well, that is a similar place. If you have plenty of money sloshing about coming from some commercial process you probably disagree with, whether you're a SV day-in-the-life-of employee or a social sciences professor, you probably can have plenty of ideas that are never disproven because you're so insulated.
That's not why, particularly. They do so for various reasons:
- they compare the reality of capitalism with a nonexistent nirvana, rather than the reality of the alternatives. They haven't run the real counterfactual
- they gravitate to any philosophy that they're familiar with instinctively: most students are young, and they conceptualise "fairness" in terms of a loving parental figure with resources meting things out to them, and they think of the government in a similar way
- they believe countries they have heard are nice to live in, normally Scandinavian countries, aren't capitalist
- they don't know the realities of real non-capitalist countries such as the USSR or pre-capitalist China, or present-day Venezuela (not truly non-capitalist, but the central planning around their oil is their main problem), or East Germany, or Cuba
- they have gone to university, the only place where bad ideas can survive and be propogated out into the world
