Used by Marxist theorists to describe anything associated with capitalists, including manufacturers, merchants, and small business owners such as shopkeepers. These groups were the opposite of the proletariat, or working people. Bourgeois has come to refer simply to the middle classes, those between the upper classes and the working classes on the social scale. The term is often used in a derogatory sense to refer to anything conventional, respectable, etc., as in "bourgeois values."
