Governments provide the parameters for everyday behavior for citizens, protect them from outside interference and often help them with their material needs. While the role of government has changed over the years, it remains a necessary part of society. Governments make laws and ensure that they are enforced, and they provide services like education and healthcare. Governments also regulate access to common goods that are essential for everyone in a society, such as the air we breathe and public lands and wildlife.
Historically, governments have served many purposes, including ensuring that people have the basic necessities of life and preventing social unrest. Today, the role of government has expanded to include a variety of additional functions, such as managing externalities and addressing market failures that the private sector is either unwilling or unable to address. Governments are also responsible for providing services that the private sector is unable to or unwilling to provide, such as national defense, the environment and property rights.
The way that a government is organized determines its power and function. There are many different forms of government, with each having its own rules, laws and functions. These include the rule of the majority with respect to minority rights, limited government and a Bill of Rights that limits the power of officials while guaranteeing the rights of individuals, and an independent judiciary that judges decisions and provides checks and balances.
Some of the main functions of government are collecting taxes, regulating free markets, and distributing wealth through programs such as social security and welfare. Governments also provide services that cannot be provided by the private sector, such as national defense and maintaining infrastructure. Some governments spend more than they make, which requires them to borrow money in order to cover the deficit. One way that they do this is by selling securities, such as bonds, to the public. This allows the government to borrow money from investors, who get paid back at some point in the future for the amount that they loaned to the government.
In addition to raising and spending funds, most countries draft budgets that outline their plans for the future. These include the goals they are trying to achieve, how they expect to reach those goals, and how they intend to allocate funds for various services such as education, police departments and public parks. These budgets also include details of the country’s revenue sources, such as taxes, fees and other payments, as well as its expenses, such as payroll and utilities. The government will then use this information to estimate its future income and expenditures. If the government estimates that it will not be able to meet its financial obligations, it will create a plan for how it will raise money in the future to avoid defaulting on its debt. This plan may include changing the way it collects or charges for its services, increasing taxes, decreasing expenses or borrowing from other sources.
