What makes the existence and the evolution of society possible is precisely the fact that peaceful cooperation under the social division of labor in the long run best serves the selfish concerns of all individuals. The eminence of the market society is that its whole functioning and operation is the consummation of this principle.
Ludwig von MisesThe capitalistic social order, therefore, is an economic democracy in the strictest sense of the word. In the last analysis, all decisions are dependent on the will of the people as consumers. Thus, whenever there is a conflict between the consumers' views and those of the business managers, market pressures assure that the views of the consumers win out eventually.
