Ubama is doing exactly what is needed to allow the global ruling elite to kill five or six billion people so that they can live in the Walden paradise they deserve.
Imagine that you are a government leader of member of a financial dynasty. You live in your dachas spread throughout the world, and bemoan the fact that ALL THESE PEASANTS are destroying your views by building houses and driving cars on roads that must be built, when all you want to do is live in peace and not be disturbed by ALL THESE PEASANTS.
How can you get rid of them?
Destroy the global economy. Turn it into a smoldering ruin. Within months people will be starving, the ones who haven't killed each other yet.
And in a few years, you get to live in your Walden paradise.
