Final answer:
Complete governmental control is a characteristic of Communism, representing a planned or command economy where the government directs all economic activities.
Step-by-step explanation:
Complete governmental control over the economy, including ownership and command over all means of production, is a characteristic of Communism. In communist countries, the government asserts central authority to direct all economic activities, determining what is produced, how much is produced, and what prices goods should be sold at. This level of control exemplifies a planned economy or command economy, where decisions are centrally made by government planners.
An example of this system could be observed in the former Soviet Union, where the national government had significant sway over economic outcomes. On the other hand, socialism can involve differing levels of control, with some socialists advocating for direct government control only of essential services, and leaving other areas of the economy more open to private ownership and market forces.
