The worker may break the process down, but he never voluntarily converts himself into a lifelong detail worker.  This is the contribution of the capitalist, who sees no reason why, if so much is to be gained from the first step--analysis--he should  not take the second step as well as the first.  That the first step breaks up only the process, while the second dismembers the worker as well, means nothing to the capitalist, and all the less since, in destroying the craft as a process under the control of the worker, he reconstitutes it as a process under his own control.  He can now count his gains in a double sense, not only in productivity but in management control, since that which mortally injures the worker is in this case advantageous to him (54-55).
