Principles of the "socialist economic system, in which the means of production are socialised and the entire national economy directed by plan" and the rules of democratic centralism, are also laid out. "Socialist ownership" takes two forms: state ownership especially of natural resources, the means of industrial production, public transportation and communications, banks and insurance companies, mass media and health, educational, and scientific facilities; and cooperative ownership, which is the property of people's cooperatives (Art. 8). Small private enterprises "based on [owner's] personal labour and excluding exploitation of others' workforce" are permitted within limits (9) formally; this in practice concerned agriculture. Personal ownership of consumer goods, "family homes, and savings earned through labour" is guaranteed, as is inheritance of such property (10).
