Explanation:

The invisible hand is a metaphor that expresses in economics the self-regulating capacity of the free market, Smith manifests it in the work "The Wealth of Nations".

The greater importance of the invisible hand increases as society develops and the division of labor grows. With the existence of this natural order makes government intervention unnecessary in most matters and it is precisely that Adam Smith identifies with Laissez Faire. The work of the government, therefore, must focus on internal and external defense, on administering justice and on providing public goods, the rest must be done by the invisible hand. Through an example Smith demonstrates how the invisible hand encourages or discourages production, as well as how the market regulates prices. The example was: in a man named Jhon while he ate his breakfast, he admired the wooden vulture he had made. Suddenly he comes up with an idea of sculpting more vultures and selling them for $ 200 each, since with those big profits he would get rich and thus he could get the things he had always dreamed of.
