Note 967 — Chapter III · : MARXISM

This demonstration implies that the wages drawn by the worker is necessarily only just equal to the value of the means of his subsistence. It is the old classic law of Turgot and Ricardo over again, which Lassalle, Marx’s contemporary and rival, graphically called the “brazen law of wages.” We are simply given a more scientific demonstration of it, that is all.

The demonstration is based upon a postulate which ought first to have been proved, namely, that the quantity of labour necessary to keep the worker alive is always less than the quantity which he provides for his master. But what is there to prove that a man who works ten hours a day does not require all those ten hours to produce sufficient for his upkeep? Is there some natural law that supports this contention? Marx simply regards it as an axiom and attempts no proof. Everyone would admit it to be true in a general way—as a kind of empirical law. For were it true that man’s labour was wholly absorbed by the necessaries of life there would be no increase of numbers, no saving of capital, and civilisation, which is the product of leisure, would never have been possible.

What we have here is the Physiocratic “net product” once again, with this difference, that instead of being confined to agricultural labour it is now regarded as an attribute of labour of every kind.
