Explanation:

Justification: Classical economists observe that markets generally regulate themselves, when free of coercion. Adam Smith referred to this as a metaphorical "invisible hand," which moves markets toward their natural equilibrium. So, classical thought is also known as the non-interventionist school. As per them, markets function best without  government interference. In contrast to classical economics, Keynesian economics supports policies such as government intervention, deficit spending, control of the money supply, and a progressive income tax to counter recession and income inequality.
