Governments play a vital role in society. They protect citizens from violent extremism and the worst vicissitudes of life, they provide public goods such as healthcare, education and infrastructure. They also regulate the economy, ensure fair competition in the private sector and address deficits. Governments also enforce laws, provide security and ensure justice for all through police forces and the judicial system. They maintain national defence and carry out diplomatic relations with other countries.

The nature of government varies over time and from place to place. It can be described as a monarchy, an oligarchy, a republic, a democracy (direct or representative), a communist regime or an autocracy. Governments can also take different forms: they may be small or large, centralist or federalist. They can also have many or few functions, and they can be based on political-ideologies such as libertarianism, egalitarianism, capitalism or socialism.

During the early years of American history, there were battles over who should be in charge and what role government should play. These fights were partly about race and identity, as the structure of government had been created to protect slavery.

Since then, there have been arguments about how much power and responsibility a government should have. There have been debates about whether a government should be in charge of taking care of people, or whether it should be in charge of making laws. Some governments have done both, while others have only focused on one.

Most governments now have a mixed set of roles, balancing between protecting and providing. They still have a role to play in taking care of their citizens, but they are less and less concerned with making laws. In terms of protecting their citizens, they do this through a combination of measures:

They create a safety net by providing healthcare, education and income support. They also build and maintain infrastructure. They regulate the economy, ensuring fair competition and encouraging entrepreneurship. Governments also manage externalities, such as pollution and environmental degradation. They are responsible for national defence and policing, and they uphold human rights, including freedom of religion or belief and freedom of speech.

In order to perform these tasks, governments need to raise revenue to fund them. This is done through taxes, which are levied on incomes, property and sales. They also draw up budgets and decide how the money raised will be spent. At the local level, this often includes funding for police and fire departments, schools and hospitals. At the national level, it might include funding for roads and railways.

Governments should be transparent and accountable to their citizens, with openness and transparency being key principles. Citizens should be able to access information about the processes and statistics that are used in deciding policy. They should be able to comment and participate in the process of decision-making, and they should be able to see what is being done with their taxes. The people’s right to know is essential for a democratic society.
