That is that if the rate of profits are not equal then as you increase wages from zero and try to go to the maximum, you find that you cannot reach the maximum because some rate of profits turn negative before other reach zero, which only reveals existence of some constraint on the system. This, in my view was behind Sraffa's basic argument when he argues that all prices must change when rate of profits change given the total output constant. This is also behind the discovery of the Standard commodity. The question was: why should prices change when distribution changes? The answer was: to redress the deficit or surpluses that would emerge in different sectors; it was seen as an internal necessity of the system. Only from this ground, he could ask: so if I remove this cause from some sector then that commodity will have no reason to change given the cause. And so the Standard commodity was discovered. I, of course, would welcome some suggestions of developing some internal dynamics of the system--more in the line of quantum mechanics, I guess--which would also prove the above proposition. If you have any idea, please send it to me off list. Currently we are working out the dynamics of the gravitation mechnism given CRS to see if it, in any case, works.
