Earlier quoted context omitted.
How the hell do you allocate resources with maximal efficiency, without either a central authority or trade? Maybe I'm just an old stick in the mud, but those two are "I tell you what you want" and "You tell me what you want", and I don't see the third option.
I don't think it matters which. We are potentially going to go from 7 billion people to 9 billion people. At the 7 billion mark we would need 5 planets worth of resources if everyone were to consume at the level Americans do, so where does that leave us is a few decades while the poorer nations are evolving at such a rapid pace? Ideally we get engineers and scientists to start with x amount of resources and x number…
You're assuming that we are already making maximal use of all available resources. We aren't; we're not even close. The reason the "poorer nations" are poor is politics, not lack of resources.
