Communism is dead, socialism is dead, fascism is dead, god is dead, and now market fundamentalist capitalism is dying.
Of course all these things still have their True Believers, but as time goes on the ranks of those true believers dwindle and it becomes increasingly difficult to find serious and widely educated thinkers among them.
This is interesting. Ideology with a capital I is a big part of how human beings model and conceptualize the world. I think what we're seeing is that our cognitive modeling capabilities have limits. Our models break down. It honestly reminds me of the trends that sweep through the computer programming world: object oriented, aspect oriented, functional, MVC, late binding, strong typing, weak typing, multiparadigm, templates, and so on... all work well for a while and then show their weaknesses.
P.S. The big thing that killed market fundamentalism for me was doing a stint in business consulting and seeing what the average rich person actually is: a glorified street hustler. I was once a bit of a Randian... it was a real "the emperor has no clothes" moment. (I can think of a few rich folks who remind me of Rand heroes... a very, very, very few. I don't think I would run out of fingers. Elon Musk would be at the top of the list. Oh, but wait, his enterprises are quasi-philanthropic ventures...)
