I tend to agree with your theory about a consortium ruling the planet in the near future. It might not even take 3-4 generations. I think the trend is accelerating.
You are right, this does not bode well for those who’ve had higher living standards as a result of militarism, control of global natural resources, and nationalism. It seems pretty clear that “the elite” do not have the same sense of “patriotism” as the plebs.
