Labor theory of value

Definition and stakes

John Spargo,  Socialism: A Summary and Interpretation of Socialist Principles

“ Stated in the simple, crude form, that the quantity of human labor crystallized in them is the basis and measure of the value of commodities when exchanged against one another, the labor theory of value is beautifully simple. At least, the formula is simplicity itself. At the same time, it is open to certain very obvious criticisms. It would be absurd to contend that the day's labor of a coolie laborer is equal in productivity to the day's labor of a highly skilled mechanic, or that the day's labor of an incompetent workman is of equal value to that of the most proficient. ”

Robert Rives La Monte,  Socialism: Positive and Negative

“ This wasted labor does not count in measuring value. The only labor that counts is the labor that is socially necessary under normal conditions for the production of the given commodity. Again, labor spent to produce a useless article does not produce value. To produce value the labor must serve to satisfy human wants. Now, I think this is quite clear so far. We know what surplus-value is. We know what value is and how it is measured. Let us now see what is meant by the Value of Labor-Power. ”

Portrait of Samuel Peter Orth Samuel Peter Orth,  Socialism and Democracy in Europe

“ Labor-time, therefore, is the universal measure of value, the common medium that determines values. But this labor is acquired in the open labor market by the capitalist at the lowest possible price, a price whose utmost limit is the bare cost of living. The reward for his labor is called a wage. ”
