The decisive weakness in neoclassical and neo-Keynesian economics is not the error in the assumptions by which it elides the problem of power. The capacity for erroneous belief is very great, especially where it coincides with convenience. Rather, in eliding power - in making economics a nonpolitical subject - neoclassical theory destroys its relation to the real world. In that world, power is decisive in what happens. And the problems of that world are increasing both in number and in the depth of their social affliction. In consequence, neoclassical and neo-Keynesian economics is relegating its players to the social sidelines where they either call no plays or use the wrong ones. To change the metaphor, they manipulate levers to which no machinery is attached.
