China to economically surpass US in 10 years? Latest issue of National says "China will surpass the United States as the world's largest economy in 10 years...". I am skeptical on this because of the damage done by one child policy. I know a couple in China who each has a mother and father. And each of their parent has 6 surviving parents. So basically two kids has to support 4 parents and 6 grandparents.
