Keynes contents in General Theory that the monetary market logic of the aggregate real wage in the monetary production economy conveys: (i) the determination of the average real wage rate, the level of employment, and the possibility of involuntary unemployment through the interaction of the monetary markets and the goods markets; and (ii) the determination of the money wage rate through the bargains of the firms and the workers as a market-theoretical stability condition of the economic system. Accordingly, (iii) the money wage claims of labour (in conformity with changes of the average labour productivity) do not alter the distribution of income between capital and labour; and (iv) the struggle about the money wages by different groups of workers is actually a zerosum game over the distribution of the aggregate real wage between the different fractions of the working class. The paper discusses Keynes´s contention in the context of the monetary-keynesian theory of the endogenous-money monetary production economy.
