He simply genuinely believes allowing the market to operate as close to freely as possible is what generates the greatest amount of prosperity for everyone. The fact that the U.S. is the world's strongest economy by far should be proof enough, but apparently people still prefer to hate success
My point is that to think that one knows what is best for society is similar to thinking that one knows how best to allocate goods. It just isn’t possible to know. Any capitalist will surely agree that value is purely subjective.
The capitalist believes the exact opposite – that he can never claim to be a better planner than "nature itself" so we should admit defeat and let things transpire naturally while we each focus on our individual lives and businesses, which presumably we know how to live or run better than the state.
