Dear Fred, I may be wrong but what I am arguing is that a "condition for" cannot be identified as a "reason for"...It is something similar to the joke Marx makes at a certain point in Capital: the condition for digestion is a good stomach. Actual digestion, on the other hand, needs something more..." That is, the condition for the existence of surplus value cannot be identified with an explanation for why it exists. The actual difference between L and Ln in capitalism is a product of the history of human productivity, human working day and wages. The convergence of these three elements is what makes sure that the condition for the existence of surplus value actually takes place. Do you agree with this? Paulo "Fred B.
