The concept of slavery as private property is condemned by the Church, which classifies it as the stealing of a person's human rights. Theft According to the Catechism, theft or stealing means "usurping another's property against the reasonable will of the owner" though exclusion exists for someone in great need to survive. "Unjustly taking and keeping the property of others" considered as theft, even if the act is outside the scope of civil law. Cardinal Christoph Schönborn once used the example of Saint Augustine's theft of his neighbor's pears in his youth, as recorded in his Confessions. Cardinal Schönborn points out that Augustine still has "pangs of conscience over a childish theft" even when he became grown person, indicating that human conscience is very aware of acts of theft, even if the act itself is legal under civil law. The following acts are also considered as violation of the seventh commandment: price manipulation to get advantage on the harm of others, corruption, appropriation of the public goods for personal interests, work poorly carried out, tax avoidance, counterfeiting of checks or any means of payment, any forms of copyright infringement and piracy, and extravagance. Social justice The papal encyclical Rerum novarum discusses the relationships and mutual duties between labor and capital, as well as government and its citizens. Of primary concern was the need for some amelioration for "the misery and wretchedness pressing so unjustly on the majority of the working class". The encyclical supported the right to form unions, rejected socialism, communism and unrestricted capitalism, and affirmed the right to private property. Church interpretation of the seventh commandment teaches that business owners should balance a desire for profits that will ensure the future of the business with a responsibility toward the "good of persons". Business owners are required to pay their workers a reasonable wage, honor contracts, and abstain from dishonest activity, including bribery of government officials. Workers are required to do their jobs conscientiously, as they have been hired to do them, and to avoid dishonesty in the workplace, such as using office goods for personal use without permission (embezzlement). The Church teaches that a balance should exist between government regulation and the laws of the marketplace. It deems that sole reliance on the marketplace (pure capitalism) insufficiently addresses many human needs, while sole reliance on government regulation (pure socialism) "perverts the basis of social bonds".
