Few people defend freedom as a moral value. I’ve been reading Ayn Rand’s “Capitalism, the Unknown Ideal” in which she does just that. We can defend freedom or capitalism on a utilitarian bassis - greatest good for greatest number of people, but that opens us up to statistical manipulation or anecdotal evidence that show that some people are hurt by a free society.
Rand defends capitalism and freedom on a moral basis, and in the process shows how everyone benefits, and that the poor benefit to a much greater degree than do the rich.
