 version of socialism is more popular than my version of capitalism. I'm in a minority because I believe that to embrace the kind of capitalism that I'm talking about, we have to challenge very fundamental beliefs about the purpose of life and about morality. I believe that capitalism can only stand on a foundation of self-interest, of individual self-interest on the morality of individuals pursuing their own happiness. And yet, at least since the rise of Christianity, the dominant moral view has been that individual sacrifice is the moral purpose of life, that the purpose is other people's well-being, not your own. That has been secularized, was secularized in the 19th century by primarily German philosophers, but a number of German philosophers, and then completely secularized by socialism.
