The fundamental contradiction of capitalism is capital vs. wage labor, a social relationship between the classes involved, capitalists and workers (also known as the bourgeoisie and the proletariat). The relationship is one of domination and subordination. Domination is perpetrated economically, ideologically, and politically. And the working class resists in all three fields. The class struggle is constant and antagonistic. It can only be resolved by social transformation, by the end of capitalism.
