Berkeley people are not dumb. I had a learning partner who had a degree in computer science from Berkeley who is light years smarter than me. The problem is that Leftism and Socialism in various shades from strong RED to Pink were simply the accepted academic university norms and still are until today. [I was horrified to see this in NYU.] Philosophers today are not visionaries and tend to be quite superficial thinkers. [With the exception of Kelley Ross.] I think it was easier in the USSR to see the problems with the system of communism more than in the USA where people could dream about a socialist paradise without having to feel the jackboots on their necks.
