what does rerum novarum teach about ownership and use of private property
Rerum novarum Although the Encyclical follows the lines of the traditional teaching concerning the rights and duties of property and the relations of employer and employee, it applies the old doctrines specifically to modern conditions.[12] Leo first quotes Thomas Aquinas in affirming that private property is a fundamental principle of natural law. He then quotes Gregory the Great regarding its proper use: ""He that hath a talent, let him see that he hide it not; he that hath abundance, let him quicken himself to mercy and generosity; he that hath art and skill, let him do his best to share the use and the utility hereof with his neighbor."[13] Liberalism also affirms the right to private property, but socialism and communism do not.
Socialist economics The ownership of the means of production varies in different socialist theories. It can either be based on public ownership by a state apparatus; direct ownership by the users of the productive property through worker cooperative; or commonly owned by all of society with management and control delegated to those who operate/use the means of production.
