"Capitalist ideology in general, Žižek maintains, consists precisely in the overvaluing of belief - in the sense of inner subjective attitude - at the expense of the beliefs we exhibit and externalize in our behavior. So long as we believe (in our hearts) that capitalism is bad, we are free to continue to participate in capitalist exchange. According to Žižek, capitalism in general relies on this structure of disavowal. We believe that money is only a meaningless token of no intrinsic worth, yet we act as if it has a holy value. Moreover, this behavior precisely depends upon the prior disavowal - we are able to fetishize money in our actions only because we have already taken an ironic distance towards money in our heads."
