Mutualism (economic theory)
Mutualism is an anarchist school of thought and economic theory that advocates a socialist society based on free markets and usufructs, i.e. occupation and use property norms. One implementation of this system 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 which it uses as its basis for determining economic value. According to mutualist theory, when a worker sells the product of their labor, they ought to receive money, goods, or services in exchange that are equal in economic value, embodying "the amount of labor necessary to produce an article of exactly similar and equal utility".
Mutualism (economic theory)
Mutualism was popularized by the writings of anarchist philosopher Pierre-Joseph Proudhon. Mutualists are opposed to individuals receiving income through loans, investments and rent under capitalist social relations. Although personally opposed to this type of income, Proudhon expressed that he had never intended "to forbid or suppress, by sovereign decree, ground rent and interest on capital. I think that all these manifestations of human activity should remain free and voluntary for all: I ask for them no modifications, restrictions or suppressions, other than those which result naturally and of necessity from the universalization of the principle of reciprocity which I propose". As long as they ensure the worker's right to the full product of their labor, mutualists support markets and property in the product of labor, differentiating between capitalist private property (productive property) and personal property (private property). Mutualists argue for conditional titles to land, whose ownership is legitimate only so long as it remains in use or occupation (which Proudhon called possession), a type of private property with strong abandonment criteria. This contrasts with capitalist non-proviso Lockean sticky property, where owners maintain a property title more or less until they consent to gift or sell it.
Mutual savings bank
A mutual savings bank is a financial institution chartered by a central or regional government, without capital stock, that is owned by its members who subscribe to a common fund. From this fund claims, loans, etc., are paid. Profits after deductions are shared among the members. The institution is intended to provide a safe place for individual members to save and to invest those savings in mortgages, loans, stocks, bonds and other securities and to share in any profits or losses that result. The members own the business.
