132 The root and font of this defection in economic and social life from the Christian law, and of the consequent apostasy of great numbers of workers from the Catholic faith, are the disordered passions of the soul, the sad result of original sin which has so destroyed the wonderful harmony of man's faculties that, easily led astray by his evil desires, he is strongly incited to prefer the passing goods of this world to the lasting goods of Heaven. Hence arises that unquenchable thirst for riches and temporal goods, which has at all times impelled men to break God's laws and trample upon the rights of their neighbors, but which, on account of the present system of economic life, is laying far more numerous snares for human frailty. Since the instability of economic life, and especially of its structure, exacts of those engaged in it most intense and unceasing effort, some have become so hardened to the stings of conscience as to hold that they are allowed, in any manner whatsoever, to increase their profits and use means, fair or foul, to protect their hard-won wealth against sudden changes of fortune. The easy gains that a market unrestricted by any law opens to everybody attracts large numbers to buying and selling goods, and they, their one aim being to make quick profits with the least expenditure of work, raise or lower prices by their uncontrolled business dealings so rapidly according to their own caprice and greed that they nullify the wisest forecasts of producers. The laws passed to promote corporate business, while dividing and limiting the risk of business, have given occasion to the most sordid license. For We observe that consciences are little affected by this reduced obligation of accountability; that furthermore, by hiding under the shelter of a joint name, the worst of injustices and frauds are penetrated; and that, too, directors of business companies, forgetful of their trust, betray the rights of those whose savings they have undertaken to administer. Lastly, We must not omit to mention those crafty men who, wholly unconcerned about any honest usefulness of their work, do not scruple to stimulate the baser human desires and, when they are aroused, use them for their own profit.
