I deal with a lot of young people, and I see absolutely no sign of this.
They seem all to willing to give Socialism it’s “full, fair shot”, as none of them have lived through the Cold War and hence they’re clueless about the downside.
To the extent there is a change some are becoming Libertarians (shut down the NSA, legalize pot, get your nose out of who or what I sleep with, etc.)
They’ll always believe that socialism works, but the right people have never run it.
