“Here, Marx speaks very clearly about a 'rebellion' of the working class in the 'political' sphere, which forces the State to enforce a shortening of labour time'. This 'rebellion' against the system induces a response that simultaneously represents both a capitalistic development of the machine system, and a consolidation of its domination over the working class. It is different,

however, so soon as the compulsory shortening of the hours of labour takes place. The immense 'impetus it gives to the development of productive power, and to economy in the means of production, imposes on the workman increased expenditure of labour in a given time, heightened tension of labour-power, and closer filling up of the pores of the working day, or condensation of labour to a degree that is attainable only within the limits of the shortened working day ... In addition to a measure of its extension, i.e., duration, labour now acquires a measure of its intensity or of the degree of its condensation or density. (36)
It is at this point that the phenomena typical of large-scale capitalist industry make their appearance.

So soon as the shortening becomes compulsory, machinery becomes in the hands of capital the objective means, systematically employed for squeezing out more labour in a given time. This is effected in two ways: by increasing the speed of the machinery, and by giving the workman more machinery to tend”
