“To recapitulate: the exchange-ratio subsisting between commodities and money is everywhere the same. But men and their wants are not everywhere the same, and neither are commodities. Only if these distinctions are ignored is it possible to speak of local differences in the purchasing power of money or to say that living is dearer in one place than in another.”

Austrian economist and social theorist of the early-to-mid 20th century, Ludwig von Mises is best known for his rigorous defense of classical liberalism and free-market economics. His work in praxeology—an a priori method of social science—shaped modern libertarian thought, while his critiques of socialism and central planning remain foundational in economic theory.
