A resource allocation method that requires that I serve my fellow man in order to have a claim on what he produces is far more moral than government resource allocation. The government can offer, justifying it with one reason or another, "Williams, you don't have to serve your fellow man in order to have a claim on what he produces. Through the tax code, we'll take what he produces and give it to you." Of course, if I were to privately take what my fellow man produced, we'd call it theft. The only difference is when the government does it, that theft is legal but nonetheless theft - the taking of one person's rightful property to give to another.
