I strongly urge you to read this article from the philosophy blog at the New York Times. It really sets out that philosophical grounding of the two extremes of policy making in the U.S. today. Be warned though, when the author describes Nozick as a liberal, she means it in the classical sense, which is closer to what we would consider the libertarian position today.

Please, please think about this when you cast your policy arguments in moral terms.
