Just as armed military force can be misused to bully, oppress or subjugate the free will of a people or a nation, so also, the economic powers can be similarly misused. If a World-State comes about, and if it is able to gain ascendancy with respect to military forces and armaments, it will still be subject to instability resulting from economic powers being left outside its province of control. Thus, the entire structure is subject to being undermined in this way.
Sri Aurobindo notes: “The World-State even in its early and imperfect organisation must begin not only to concentrate military force in its hands, but to commence consciously in the beginning what the national State only arrived at by a slow and natural development, the ordering of the commercial, industrial, economic life of the race and the control at first, no doubt, only of the principal relations of international commerce, but inevitably in the end of its whole system and principles. Since industry and trade are now five-sixths of social life and the economic principle the governing principle of society, a World-State which did not control human life in its chief principle and its largest activity would exist only in name.”
