It is individual choices in response to personal subjective value judgments that ultimately determine market phenomena—supply and demand, prices, the pattern of production, and even profits and losses. Although governments may presume to set “prices,” it is individuals who, by their actions and choices through competitive bidding for money, products, and services, actually determine “prices”. Thus, Mises presents economics—not as a study of material goods, services, and products—but as a study of human actions. He sees the science of human action, praxeology, as a science of reason and logic, which recognizes a regularity in the sequence and interrelationships among market phenomena. Mises defends the methodology of praxeology against the criticisms of Marxists, socialists, positivists, and mathematical statisticians. Mises attributes the tremendous technological progress and the consequent increase in wealth and general welfare in the last two centuries to the introduction of liberal government policies based on free-market economic teachings, creating an economic and political environment which permits individuals to pursue their respective goals in freedom and peace. Mises also explains the futility and counter-productiveness of government attempts to regulate, control, and equalize all people’s circumstances: “Men are born unequal and … it is precisely their inequality that generates social cooperation and civilization.”
