Chinese did have a dark age from the Opium War (the Brits pushed opium as a nation) to Nixon's lifting up the embargo (a proof how a unified embargo can hurt a country). When the basic survival is food, shelter and basic medical delivery, of course they do not have time for inventions and other improvements for better life.
Uncle Deng should be given a Nobel prize for lifting millions from starving but one to Obama for doing nothing and one economist for theories that do not work. The Nobel prizes seemed to be given to enemies of China: a writer who gave up Chinese citizenship and Dali Lama. It indicates the stupidity of the Nobel Prize committee. If they give me one (a joke), I will throw it to the garbage (but I will keep the money) can as it is totally meaningless and too political. LOL.
