Answer:
The invisible hand is the metaphor used by the moral philosopher and economist Adam Smith of the social mechanism he theorized that, in the free market, the pursuit of individual self-interest serves the common good, that is, people act as if guided by an "invisible hand".
The invisible hand mechanism requires a few criteria: price, efficiency, market and greed. An individual does high quality work efficiently, resulting in a good and cheap product. He may sell it on the market at a price acceptable to all parties. The buyer receives the commodity they need and the seller / producer receives compensation for their work. In the store, everyone gets what they want.
Before the Enlightenment, pursuing one's own self-interest was considered contrary to the common good. According to Adam Smith, "it is the self-interest of individuals that enables the division of labor to function." In addition, Smith stated that people's aspirations to promote their own economic interests in the best possible way have positive consequences for society as a whole. To this phenomenon, Smith invented the name invisible hand.
