In the third volume of Capital, Karl Marx clearly named the ultimate aim of communism and the measure of its realization: the freedom granted to each individual, as soon as the work necessary to satisfy the needs of all is collectively organized. The accuracy and validity of this neglected and forgotten aspect of his thought is once again evident in the current situation. At the beginning of the 21st century, the realm of non-freedom is expanding. The theft of working time at the expense of wage earners has taken on the dimensions of a global plunder. The eight-hour workday, won through hard struggle, is under threat. We are witnessing the end of a phenomenon that has been observed for more than a hundred years: the reduction of working hours. And unemployment, which plunges many people into misery, seems to have no impact on this. The masters of wage labor have decided to turn back the clocks by all means, to rewind the hands, and to seize every single moment: human surplus labor still represents the most profitable resource for the market economy. This aggressive appropriation of time, waged like a crusade through so-called reforms, is met with considerable resistance. It is urgently time to resume a struggle that has lasted for more than a hundred years.
