The author of the article only forgot a little detail.. the population size and the urbanization phenomena...

Only when this stop to happen, we will be able to see the real size of the china economy.. not to mention the "last drop", when they will push efficiency into the engines, to get a little more expansion.. US and Japan already did both.. and til someone discover a new economical path.. nowhere to go for them..

So only china and the emergents will be able to grow right now, under the old economical gears..

(not to mention that nobody is making more babies anyway to fill the void)
