Explanation:

In the Wealth of Nations, Adam Smith lays out a very robust theory about how the economy works, this is why many economists consider him to be the Father of the economic science.

Adam Smith's main thesis was that people, acting own their own interest, were guided by the invisible hand, leading to positive results that benefited the whole of society, even if that was not the main goal of economic actors in first place (their main goal being furthering their own interests).

For this reason, Smith thought that most government intervention was unecessary, since according to him, economic actors tended to self regulate in the market, and to produce an optimal result for society. He did justify some government intervention though: in the military, in the judicial system, and in some basic social services in order to care for the poor, the elderly, and the sick.
