This article presents a binary economic critique of Milton Friedman's thesis that a competitive, free market, private enterprise, capitalist system is an essential condition for freedom. After identifying deficiencies in Friedman's understanding of private property and economics, this article explains how a market economy based on Friedman's flawed understanding concentrates economic power in a plutocracy, perpetuates chronic underemployment of labor and capital, and suppresses the freedom of most people. It advances a "binary economic approach" to create a more productive and democratic market system characterized by greater, more sustainable, and more widely-distributed prosperity, economic power, and individual freedom than prevails in any existing capitalist economy.
