What is the work of the …

The basic functions of the government are:

To form a more perfect Union.

To establish Justice.

To insure domestic Tranquillity.

To provide for the common defence.

To promote the general Welfare.

To secure the Blessings of Liberty.

The concept of government as provider comes next: government as provider of goods and services that individuals cannot provide individually for themselves. Government in this conception is the solution to collective action problems, the medium through which citizens create public goods that benefit everyone, but that are also subject to free-rider problems without some collective compulsion.

To promote the general Welfare - The government fulfils this function in many different ways, including monitoring the economy, businesses, and banks; maintaining the postal service, education system, roads, and public utilities like water, sewer, and electricity; regulating the safety of food and medicine.
