The Functions of Government
Government is the body that governs a country, a region or sometimes even an organization. It can have many forms, depending on the political system of the nation, which is determined by the culture and history of the people who live there. Governments have many functions, including protecting citizens from outside threats and ensuring that laws are followed. They often create and enforce taxes, which can fund these various functions.
Governments are usually organized into three branches: legislative, executive, and judicial. The people who work in the legislative branch, such as Congress and the Senate in the United States, make the laws that govern the country. The president and other members of the cabinet are under the executive branch, which carries out those laws. The judicial branch, which includes the Supreme Court and other federal courts, evaluates the laws.
Often, the government solves problems that market forces cannot, such as air and water pollution, or providing national defense. In these cases, the government punishes polluting industries on behalf of the citizens, who would otherwise be unable to file lawsuits against these corporations.
In addition to protecting citizens, governments also provide public goods, such as education, roads, and police and fire departments. These are services that are provided to all citizens without charge, and that would be difficult or impossible for private businesses to provide.
A central function of government is the maintenance of a state’s national defense, which it carries out by creating and maintaining armed forces. It also protects the nation against domestic threats by maintaining intelligence agencies, preventing the entry of aliens who may be spies or terrorists, and prohibiting the export of materials that could help an enemy.
Another key function of government is to preserve the state against external threats by making treaties and negotiating with other nations. The state also preserves itself against internal threats by monitoring the activities of its own citizens, and by deporting or imprisoning people who pose a threat to the safety or security of the nation.
The government preserves itself against natural disasters by establishing warning systems, preparing for and responding to emergencies, and providing insurance for citizens. The government also makes sure to maintain the quality of its natural resources, such as oil and water.
Governments are necessary in all societies, because they offer protection if the citizens agree to follow the rules that the government sets in place. In democratic governments, the people, through representatives they elect, decide what those rules will be. In authoritarian governments, the decision-making process is centralized in the hands of one person or group of people. Many countries combine elements of these different models, resulting in governments that limit some freedoms but protect others.
The founding fathers of the United States crafted their government to be as limited in scope as possible, and the Constitution breaks down the government into the Legislative, Executive, and Judicial branches. This is because they knew that if any one branch became too powerful, it could become oppressive.
