2. The ultimate consequences of the individualist spirit in economic life are those which you yourselves see and deplore: Free competition has destroyed itself; economic dictatorship has supplanted the free market; unbridled ambition for power has likewise succeeded greed for gain; all economic life has become tragically hard, inexorable, and cruel. To these are to be added the grave evils that have resulted from an intermingling and shameful confusion of the functions and duties of public authority with those of the economic sphere -- such as, one of the worst, the virtual degradation of the majesty of the State, which although it ought to sit on high like a queen and supreme arbitress, free from all partiality and intent upon the one common good and justice, is become a slave, surrendered and delivered to the passions and greed of men. And as to international relations, two different streams have issued from the one fountain-head: On the one hand, economic nationalism or even economic imperialism; on the other, a no less deadly and accursed internationalism of finance or international imperialism whose country is where profit is. (Papal Encyclical, Quadragesimo Anno, 15 May 1931).
2. Yet, however the earth may be apportioned among private owners, it does not cease to serve the common interest of all, inasmuch as no living being is sustained except by what the fields bring forth. Those who lack resources supply labor, so that it can be truly affirmed that the entire scheme of securing a livelihood consists in the labor which a person expends either on his own land or in some working occupation, the compensation for which is drawn ultimately from no other source than from the varied products of the earth and is exchanged for them. For this reason it also follows that private possessions are clearly in accord with nature. The earth indeed produces in great abundance the things to preserve and, especially, to perfect life, but of itself it could not produce them without human cultivation and care. Moreover, since man expends his mental energy and his bodily strength in procuring the goods of nature, by this very act he appropriates that part of physical nature to himself which he has cultivated. On it he leaves impressed, as it were, a kind of image of his person, so that it must be altogether just that he should possess that part as his very own and that no one in any way should be permitted to violate his right. (Papal Encyclical, Rerum Novarum, 1891).
