Murderous capitalism: Schmitt, Ranciere, Agamben, Derrida

The basic structure of Ranciere and Agamben's thought is Schmittian. This is not because they are politically on the same side as Schmitt of course but 1) because they both want to avoid historicism, 2) because they both have given up on the notions of capitalism and class struggle as key analytic categories and, yet for all that, 3) because they both wish to assert the primacy of the political over the cultural so as not to promote false consensus. In Schmitt the political is the master signifier of social existence for the reason that we live in a world where others—our enemies— wish to murder us (as Leo Strauss makes clear in his essay on The Concept of the Political), and politics are the means by which we resist death in that form. But for Ranciere and Agamben the figure who stands outside the community and around whom, hence, the political turns is an excluded victim. Homo sacer for Agamben and "the part that has no part" for Ranciere.
With that inversion everything changes, since in effect we are led back to the old social logics which connect politics to inclusion, compassion and benevolence but without any use of or for the concepts of inclusion, compassion and benevolence. The absence of channels to reach out to the excluded in postmarxist thought, is all the more strongly felt because, at least in its strongest forms (Badiou) it has also given up the concepts of difference, which lie at the heart of post-structuralism.
It is true that Derridean difference can be regarded as an allegorizing expression of a sense that violence between groups is no longer the motor of history (i.e. of the 'end of history' or the triumph of capital) just because that difference is not to be parsed as otherness or enemity but as what is neither the same nor the other (or both the same and the other: it amounts to the same thing.) But what is excommunicated or persecuted or put to death can never be just the other in a truly political sense, about that Schmitt was right.
What all these theories lack is an understanding of capitalism as murderous, or to put this more accurately and gently, that capitalism does not at all allay the species capacity for collective murder.
