It is the fundamental rôle of ‘formal freedom’ which is overlooked by Marxists who think that formal democracy is not enough and wish to supplement it by what they usually call ‘economic democracy’; a vague and utterly superficial phrase which obscures the fact that ‘merely formal freedom’ is the only guarantee of a democratic economic policy. Marx discovered the significance of economic power; and it is understandable that he exaggerated its status. He and the Marxists see economic power everywhere.
