Abstract All popular schools lack a consistent profit theory. Economists have no true conception of the most important phenomenon in their universe. This methodological defect persists since Adam Smith. Therefore, the theories of income and wealth distribution are wrong by logical implication. If the conclusions of a theory do not find any counterpart in reality the fault lies in the premises. In order to rectify distribution theory, it is necessary to substitute the conventional subjective-behavioral axioms with objective-structural axioms. A major result of the present paper is that distribution is not governed by marginal productivity but by the distributed profit ratio.
