Slovoj Zizek, The Plague Of Fantasies, Verso, 1997.
The necessary failure here is structural: it is not simply that, because of the empirical complexity of the situation, all particular progressive fights will never be united, that ‘wrong’ chains of equivalences will always occur (say, the enchainment of the fight for African-American ethnic identity with patriarchal domination and homophobic attitudes), but rather, that occurrences of ‘wrong’ enchainments are grounded in the very structuring principle of today’s progressive politics of establishing ‘chains of equivalences’: the very domain of the multitude of particular struggles, with their continuously shifting displacements and condensations, is sustained by the ‘repression’ of the key role of economic struggle. The Leftist politics of the ‘chains of equivalences’ among the plurality of struggles is strictly correlative to the abandonment of the analysis of capitalism as a global economic system — that is, to the tacit acceptance of capitalist economic relations and liberal-democratic politics as the unquestioned framework of our social life (128)
