The essence and the glory of the free market is that individual firms and businesses, competing on the market, provide an ever-changing orchestration of efficient and progressive goods and services: continually improving products and markets, advancing technology, cutting costs, and meeting changing consumer demands as swiftly and as efficiently as possible.
Murray Newton Rothbard (1978). “For a New Liberty: The Libertarian Manifesto”, p.242, Ludwig von Mises Institute
