In a capitalist economy, a character mask ("Charaktermaske") is the functional role with which a person relates and is related to in a society composed of stratified social classes, especially in relationships and market-exchange transactions; thus, in the course of buying and selling, the commodities (goods and services) usually appear other than they are, because they are masked (obscured) by the role-playing of the buyer and the seller. Moreover, because the capitalist economy of a class society is an intrinsically contradictory system, the masking of the true socio-economic character of the transaction is an integral feature of its function and operation as market exchange. In the course of business competition among themselves, buyers, sellers, and producers cannot do business (compete) without obscurity—confidentiality and secrecy—thus the necessity of the character masks that obscure true economic motive.
