Our second Notebook analyses the contemporary production process that results in Apple’s iPhone. We move from a look at the iPhone’s production to the inner workings of profit and exploitation. We are interested not only in Apple and the iPhone, but more particularly in the Marxist analysis of the rate of exploitation at play in the production of such sophisticated electronic devices. It is necessary, we believe, to learn how to measure the rate of exploitation so that we know precisely how much workers deliver into the total social wealth produced each year.
