From a great essay posted on the pinocchio theory blog:
Marx got capitalism right as to its structural tendencies; his mistake was to think that the inevitable, and in the long run inevitably worsening, crises to which capitalism is prone were the points at which the system itself could be overthrown. But in point of fact, not only are these crises so demoralizing that they effectively work to block any hope of action to make things different, they are positively useful to capitalist domination — and even perhaps necessary to that domination. Capitalism will never resolve its “contradictions”; and a crisis is the point at which these “contradictions” come to a head. But for that very reason, crisis is the point at which capitalism is able to reinvent itself, and prolong thhe “contradictions” that are its paradoxical conditions of possibility.
There you go, fear not, the customary insanity will resume shortly.
