He produced the theory of classical economics, which stated market economies were largely self-regulating systems that were governed by natural laws of production and exchange. Smith realized that the complex functions of society and economy unintentionally, but effectively, emerged from the self-interested actions of every individual. He specifically used the term ‘the invisible hand’ to describe the unintentional social, political, and economic benefits that stemmed from individual, self-interested actions. Smith is often regarded as ‘The Father of Modern Economics’ for these ideas as they compose the early roots of liberal economics.

Keynes's thought was that speculative bubbles had to be prevented in order to avert depressions, and to rid of speculative bubbles, it was necessary to prevent large amounts of money falling into the hands of a small percentage of people. In order to avoid this, high marginal tax rates on
