In biology, the term mutualism refers to a mutually beneficial relationship between two species. The later economic theory of mutualism is based on the labour theory of value, which states that the true cost of an item is the amount of labour that was required to produce it. Hence, goods should not be sold for more than the cost of acquiring them. Mutualism is closely associated with anarchism, because its principles were set forth in the mid- nineteenth century by the French politician and philosopher Pierre-Joseph Proudhon - the first person to define himself as an "anarchist". The main tenets of mutualism are free association and free credit. In a mutualism workplace, workers with different skills form an association to create a product or service. Though dependent on each other, the workers are not subordinated as in a capitalist enterprise. Mutual banks, also called credit unions, operate on the belief that free credit enables profit to be generated for the benefit of the union's members rather than bankers. Modern-day mutualism is sometimes described as free-market socialism. Proponents of mutualism support a free market economy, but object to capitalism because of the inequalities created by government intervention. Many mutual businesses and banking establishments exist today, espousing Proudhon's Co-operative model.
