Final answer:
Government corporations are independently run, focusing on providing essential public goods and social services that might not be profitable for the private sector.
Step-by-step explanation:
Government corporations can be described as independently run organizations that provide public goods and social services. These entities operate in the interest of the public and are involved in functions that may not be profitable for private firms but are essential for society. Examples include the Tennessee Valley Authority, which provides electricity in areas not served profitably by private companies, and the Federal Deposit Insurance Corporation, which protects consumers within the banking industry.
Further examples of services provided by the government are roads, public education, hospitals, and public welfare. Sometimes, the government competes directly with private firms, like in the case of the United States Postal Service, which provides similar services to private couriers.
