Adam Smith suggested that unfettered capitalism will not be good for us. That is Part 2 of his famous book which the neoliberals fail to mention.
I used to be a libertarian. When I realized that my education was funded mostly by taxpayers, I would not be able to understand things like libertarianism in the first place.
I can't see libertarianism working until most of the people are working with the principles of this "religion." Until then, we need a system that embraces both sides of the socialist/capitalist paradigm.
