"Mutualism is an economic theory and anarchist school of thought that advocates a society with free markets and occupation and use property norms. One implementation of this scheme involves the establishment of a mutual-credit bank that would lend to producers at a minimal interest rate, just high enough to cover administration. Mutualism is based on a version of the labor theory of value holding that when labor or its product is sold, in exchange it ought to receive goods or services embodying "the amount of labor necessary to produce an article of exactly similar and equal utility". Mutualism originated from the writings of philosopher Pierre-Joseph Proudhon."
