John Maynard Keynes was one of the most important economists of the 20th century, who developed an economic theory to solve the problems of the great depression. According to him, during an economic crisis, the government should increase its intervention and performance in the economy, in order to supply the deficiencies created by market failures. In this sense, during difficult economic times, the government would enhance its spending in different areas, like social plans, public health, labor, and education, to cover basic needs and solve the problems derived from a critical market.
