Achille Ratti.
Pope who issued the
encyclical Quadragesimo Anno (on
reconstruction of the
social order) on the 40th anniversary of
Rerum Novarum (May 15, 1931):
...a person's superfluous income, that is, income which he does not need to sustain life fittingly and with dignity, is not left wholly to his own free determination. Rather the Sacred Scriptures and the Fathers of the Church constantly declare in the most explicit language that the rich are bound by a very grave precept to practice almsgiving, beneficence, and munificence...
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.
