ways in a stage of change, moving from one thing to another; every stage has its own laws and rules, and could not be predicted based on the laws and rules that applied to some other stage (Marx, Capital 102). This way of viewing economies was but contribution of Marx as far as actual economic theory is concerned.Marxism's general economic premise relies on two main points: the labor theory of value, and the idea of surplus value. The labor theory of value represents the idea that every finished product has as its net worth the amount of work put into its production. This idea reinforces the importance of the working class, and the idea of surplus value, conversely, decries the bourgeois. Surplus value is the difference between the value of the products a worker produces and the amount he himself can purchase (McLellan 363). Marxism holds that a worker can purchase very little; that his wages will undoubtedly be so small that he can employ them to a far less satisfactory level than a bourgeois member of society can in purchasing what that worker produces (364). These two basic premises of Marxism serve to establish Marx's proclaimed injustice of the bourgeois, who can in modern terms be represented by the capitalists. Marx decries these capitalists unceasingly in his economic and philosophical thought; strangely enough, Marx himself was dependent upon the reading and writing materials provided by the bourgeois, and he never in his life visited a factory or other place harboring those workers whom he so ardently defended (Sowell 161). Marx's theories and economics can be thus simplified: Marx believed in the abolition of private property, due to the oppression of most ordinary people by the wealthy minority. He defended his theories through his two basic economic premises, the labor theory of value and the theory of surplus value. His supreme ethic- the only thing he ultimately aimed for in his theory- was historical justi...
