Under which economic system would factors of production most likely be owned by the government?

The economic system where it is most likely that the means of production would be owned by the government is a socialist system.

Explanation:

A socialist system is a type of economy where the focus is on the redistribution of wealth.  The market concept is different in a socialist economy, it is regulated and controlled to a much greater extent than the "free" market of a capitalist system. Socialist systems generally have government-run services like health care and education. They may also subsidize the cost of living for citizens like utilities and other essential services in daily life to promote greater income equality. The citizens generally pay for these services through their taxes, which tend to be higher than in capitalist systems.
