The Role of Money According to Marx

Use value of a good or service is created by all societies, capitalist and non-capitalist. The use values of such are not specifically measurable in a numerical sense; it is the level of demand by a community, or social necessity for certain goods or services. Unique to capitalist production is the exchange value of goods or services. The exchange value is the value of a good or service compared to another good or service. Understanding use value and exchange value broadly defines two kinds of economies - subsistence economies and surplus producing economies. Subsistence economies are concerned with meeting needs for social good while surplus-producing economies are concerned with meeting social needs (real or perceived) and creating excess profit. It is important to remember that a good or service becomes a commodity under capitalism because it is produced with the intention of being exchanged for a profit. “in commodity production, production necessarily implies exchange; exchange in a necessary step in the process of reproduction” (Shaikh 1977).

However, all commodities, in addition to having an exchange value, retain their use value as well. Goods that have a use value can transition to also having an exchange value when they are appropriated by private industry. An example of this is the water industry in Bolivia, which was owned and maintained by the government, and provided as a service to the public. When the water industry was privatized, the service of water was given an exchange value, for which citizens than had to pay for. Through a recent process of renationalization, the water industry was taken back under control of the government and it maintained its use value while it lost its exchange value.

The value of labor power is a laborer’s ability to do work. Labor power is a commodity under capitalism. More specifically, an important aspect of capitalism is free wage labor – in which a worker owns his labor and can sell it to which they choose at a certain wage, as he has no other commodities to sell. Like any other commodity, labor power, once used, must be renewed. The value of labor power is the value of a worker’s means of subsistence, the bundle of goods that workers consume. The value of labor power is different from a laborer’s wages, because wages can fluctuate under differing market conditions, while the value of labor power is a set value in a historical and cultural context for renewing a laborer’s ability to come a perform work each day.
