The United States operates under a limited government system. This means that the powers of the government are restricted by law, specifically the U.S. Constitution. In contrast to an unlimited government, where authorities can do as they please without legal boundaries, a limited government is characterized by its accountability to its citizens and adherence to established laws.
The Constitution itself outlines the structure of government and specifically enumerates the powers granted to federal institutions. Additionally, the Bill of Rights protects individual liberties against government overreach. By ensuring that the government operates within the boundaries set by law, the system aims to preserve freedom and prevent tyranny.
Moreover, checks and balances among the three branches of government—executive, legislative, and judicial—further emphasize the limited nature. Each branch can limit the powers of the others, ensuring that no single entity becomes too powerful.
