The worker enters into employment agreement because social conditions leave him or her no other way to gain a livelihood.  The employer, on the other hand, is the possessor of a unit of capital which he is endeavoring to enlarge, and in order to do so he converts part of it into wages.  Thus is set in motion the labor process, which, while it is a general process of creating useful values, has now also become specifically a process for the expansion of capital, the creation of profit.  From this point on, it become foolhardy to view the labor process purely from a technical standpoint, as a mere mode of labor.  It has become in addition a process of accumulation of capital.  And, moreover, it is the latter aspect which dominates in the mind and activities of the capitalist, into whose hands the control over the labor process has passed.  In everything that follows, therefore, we shall be considering the manner in which the labor process is dominated and shaped by the accumulation of capital (36-37).
