The individuals make most of the decisions related to economic activities rather than the government. Individuals can freely make decisions related to employment, accumulated capital, expenditures and the consumption of resources. The government’s only role is to provide public goods and act as a regulatory body. Public good include Education and Law and order. Another role of the government is regulating the monopolies.
