Mater et Magistra §104
Mater et Magistra: On Christianity and Social Progress
104 It is well-known that in recent years in the larger industrial concerns distinction has been growing between the ownership of productive goods and the responsibility of company managers. This has created considerable problems for public authorities, whose duty it is to see that the aims pursued by the leaders of the principal organizations—especially those which have an important part to play in the national economy—do not conflict in any way with the interests of the common good. Experience shows that these problems arise whether the capital which makes possible these vast undertakings belongs to private citizens or to public corporations.
