I think your puzzlement here might have to do with the difference between (a) a condition of zero profit and (b) a condition in which the capitalists' aggregate money holdings do not grow over time. The "fixed money" situation is compatible with positive profit. Here's a simple example. Each period the capitalists lay out 50 on labour power. The workers produce goods to the value of 100. 50 of this is necessities, purchased by the workers, and 50 is luxuries, purchased by the capitalists. Aggregate profit = capitalist consumption = 50. Total income = 100, period after period. But if we want to introduce an ongoing M-C-M', with the capitalists accumulating and income expanding, money has to flex. If money remains constant in value (and so does velocity of circulation), we'll need a larger money stock. Allin Cottrell.
