The reordering from above of the world system as a whole appears as the most overwhelming of the forces of our time. Its thrust load is so great that the old poverty cushioning systems have finally been shattered between the financialization of the economy, the geographical reordering of the accumulation cycle and the mercantile absorption of any social niche that still remained on the margin of valorization. capitalist. This panorama presented to us by Roth, perhaps in one of the most systematic syntheses that has been carried out to date, would, however, remain incomplete if he did not offer us a perspective that starts precisely "from below". This perspective could be summarized in the following question: is it possible to consider the recomposition of a social alliance that brings together the different subjects subjected to exploitation and domination in an alternative front to the current homicidal capitalism? In order to face such a challenge, it will be necessary to abandon any claim to intellectual and political hegemony of a privileged social agent. It will also be necessary to consider the transversal nature of the struggles and their urgent communication. Capitalist globalization thus redefines the essential transnational politicization of the conflict.
