>>16622>what would you say these countertendencies are?>would be interested in finding more marxist critiques of marx himself, haven't found many academically even.Its not a critique. Notice how its the "tendency" for the profit rate to fall.
Profit rate falls because the share of material capital grows in relation to the rate of organic capital. IE you have to pay more for the upkeep or replacement of machines relatively than for labour, meaning that there is less total labour in society to be put into creating new capital and more is spend on maintaining what we already have.
The counter tendency is situations where labour saving in one sectors brings down the capital cost in another. Such as improving steel production by 30%. That makes machine upkeep cheaper in terms of labour, and frees labour to build new capital.
But in practice, the implementation of labour saving technologies in non-capital-producing sectors outpaces that of capital producing sectors (because the sectors that produced non-capital commodities, such as food, clothing, etc, are smaller than those that produce or work to maintain material capital), meaning that overall, there is more and more machines that need to be maintained relatively.
