"You see as Marx said himself, the relations of production are embedded in the machinery of production. Take for example the tractor. In nineteenth century, early tractors were made by the individual craftsman in his workshop. Now they are produced on assembly lines, and at the end of assembly line stands man with stopwatch. He measures the process. To make more efficiency the worker must work harder. Now look at a man who ploughs in the field. He sits alone in cab. He moves levers and the tractor ploughs. He follows the gradient of terrain, he takes account of soil and weather. He believes he is master of the pro-cess. But at the ens of the field stands another man with stopwatch. He observes the tractor driver, makes note of his lines and turns. So certain time is allotted for the ploughing of a field, and a man's wages fixed accordingly. Now, you see,in this era of computerised  numerical control, even the man with stopwatch will be redundant, and stopwatch itselt will be incorporated into dashboard equipment."
