Mater et Magistra §115
Mater et Magistra: On Christianity and Social Progress
115 Now, if ever, is the time to insist on a more widespread distribution of property, in view of the rapid economic development of an increasing number of States. It will not be difficult for the body politic, by the adoption of various techniques of proved efficiency, to pursue an economic and social policy which facilitates the widest possible distribution of private property in terms of durable consumer goods, houses, land, tools and equipment (in the case of craftsmen and owners of family farms), and shares in medium and large business concerns. This policy is in fact being pursued with considerable success by several of the socially and economically advanced nations.
