Quadragesimo Anno: On Reconstruction of the Social Order
109 The ultimate consequences of the individualist spirit in economic life are those which you yourselves, Venerable Brethren and Beloved Children, 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.
