Ok, you're supporting the claim that technology is winning the race. May I ask a hypothetical question: if all countries had social/economic systems identical to US, with full access to US technology, democracy, political stability, etc (kinda imagine them all being US states), do you honestly believe the whole world would enjoy the same standard of living we do?
The whole world would probably enjoy much higher standard of living than we do now. Do a thought experiment, and remove any 1st-world nation from the world, and see whether it would help or hurt everyone else. In my mind, it would hurt every time, so adding more 1st-world nations would therefore help every time. There's no reason to suppose that our current proportion of rich societies to poor ones has any special significance.
Yes, it would help some large groups of people if the US were gone, but this is not because US profits from them. If anything, US loses wealth roughly in proportion to its brutality. Besides the obvious example of Iraq, there is also the "war on drugs" and its effect on the Latin American nations. Actually if everyone was 1st-world, I suspect there would be less of this pointless aggression, because US citizens aren't as able to dehumanize people who aren't poor.
