it offers me a global and more objective sight  when civil economic comments and media are not the only choice to recoginse and analyse the phenomenon happening in the world. however, i dont think  QE policy should be blamed for so much, which aimed at pulling the US out of the crisis. At most, a short-term one.  America is, after all, the biggest consuming country, an everlasting key point leading the global economic glowth, recovery of America economy would reaccelerate world growth, even though it ceated the crisis. on the contrary,  as emerging countries like china, india boom, raw material consumption becomes the engine of economic development, which promotes the soaring price of  the commodities like oil in terms of the relationship between demand and supply. Besides, low effiency of the raw materials leverages this very effect. so, for my part, technology ,especially in efficiency of raw materials,is the fundmental approach to the problem, either by import or creation.

This is not quite a zero sum game: the global economy is, after all, expanding healthily at present. From a positive perspective,that's the point.Both sides are bearing an unexpected burden ,but  progress will be the same way.
