"It's time for a genuine world government."
Yeah, that'll work. Based on the "American Plan." Then we won't have corruption, self-interest, influence of money on political power, special privilege of the rulers, weath redistribution in return for power, or a government "that suits the needs (and favors the interests) of a relatively small elite."
At what point will you understand that more centralization of power is pouring gasoline on the fire?
It might not be ideal the way it is now, but I can tell you this: even if Rothkopf is right, 6000 "oligarchs" is a hell of an improvement over a few hundred. Or one.
