>The American economy is geared to the world market, of which it requires an increasingly larger share as U.S. capital expands. If this share contracts — and it is bound to contract, should more nations turn away from the American-dominated world market towards a kind of "second world market" which restricts, or excludes, the exploitation of less-developed nations by the developed ones — it will force the internal American development into isolation and in the direction of a state-controlled economy.
Is this prediction basically in the process of being realized given the present conditions of multipolarity and the fact that the American economy has been running on state-subsidized tech bubbles? Does anyone have a statistical QRD of this tendency at hand?
