operating in the labour market, but it sets the scene of 
action in the market of the product. I elaborated this 
theory in my "Maturity and Stagnation" although I was

market to the market of product is of a more general significance 
as has already been mentioned at the start of this paper. 
It is connected with the fact that in a modern industrial 
economy real wages are not as directly controlled by 
money wages as the classics and with them also Marx were

in relation to labour, and the concentration of capital.

capitalism always involves "mechanisation" in the sense 
that more and more machines, toils, structures etc are 
needed for each worker. For example, more and more looms 
have been tended by each weaver, and the looms became
