Is it possible to read Marx as a theoretician of both the antagonistic subjectivity and the constituent practices of the collective labor force in the era of the globalization of capital and the rigid objectification of social relations? In Workers and capital, Mario Tronti undertakes in this line a powerful reading of the Marxian work and puts it in relation to the organizational experiences and the economic, social and political conditions of contemporary capitalism in force in the Italian metropolis. The complexity of today's capitalist societies is the structural translation of the class antagonism of the collective labor force that continually invents and reinvents ways and strategies of rejection of labor and of proletarian self-worth. If the processes of social constitution are not to be exhausted in the logic imposed by the current forms derived from the market, formal democracy and the State, it is necessary to delve into the foundation and phenomenology of the forms of exploitation and social constitution of the force of collective work. In this sense, the concepts of class composition and class antagonism recover a solid epistemological consistency suitable to make possible further research and political organization processes and if the premise to think of a world in which equality and justice are the result of the power of the productive subjects and not the result of their structural exploitation, then the unpublished forms of social cooperation of the latter indicate the horizon of the new political models for the societies of the future.
