The Globe and Mail featured an interesting article on how the rapid growth of emerging economies is radically reshaping the global economy. The article points out that the Chinese and Indian economies together are bigger than the United States in purchasing power parity (PPP) terms. This is not a surprise: the combined population of China and India is 2.4 billion, which is eight times larger than that of the United States. Thus, even in PPP terms the average American is eight times richer than the average Chinese or Indian. In dollar terms, the gap is even larger. It is also not a surprise that emerging economies have higher growth than more mature economies. China (and to some extent, India) has come far economically, but they still have a lot of catching up to do. It would be unwise to extrapolate recent trends far into the future.
