For what ever masochistic reason, I have started listening to interviews with Charles A. Murray. He is the perfect embodiment of the sadistic conservative you describe. He circles all these issues that are the direct result of class and economic deprivation. As a libertarian, he cannot abide any class analysis, and sees capitalism as just a law of nature. The combination of these things makes his conclusions so cruel. He is also a perfect foil for liberals, because they like him cannot abide class analysis, and see capitalism as a force of nature. They are made for each other. Two sides of the same coin. His is the white mans burden, and they play the savior.
