In his Capital, Marx throughout maintained the simplifying theoretical precondition that the value of labour is fixed and constant. However by this he mostly closed out discussing problems concerning class struggle and the organisational level of the working class from the analysis of capitalism in Capital. The connection, that increasing productivity results in proportionally higher profit only if the working class remains disorganised or its segmentation increases, receives little attention. Nevertheless, the capital immanently and necessarily aims not only increasing productivity but also deepening divisions among workers.
