"Let us start with elementals. Income and property are certainly the instruments of an individual’s freedom. Clearly the domain of choice is enhanced by increases in those dimensions. It is true not merely in the sense of expanded consumer choice but also in broader contexts of career and opportunity to pursue one’s own aims and to develop one’s own potential. Unequal distribution of property and of income is inherently an unequal distribution of freedom. Thus a redistribution of income, to the extent that it reduces the freedom of the rich, equally increases that of the poor. Their control of their lives is increased."
