Of course the economy of the world is interconnected. But we are talking about a changing of the guards and the next leader of the pack. Loh, let me remind you that the US's share of the world economy has declined from 50% after WW2 to 20% in 2010. It is forecast to decline to 18% in 2015, the year before China overtakes the US as the number 1 economic power in 2016. That means China's share of the world economy will be ahead of the US's, signalling a changing of the guards. To look at this in proper perspective, Loh, do you know what was China's share of the world economy after WW2? Almost too small to make it pass the decimal point! Now you tell me IQ has nothing to do with it? I predict that in the 2030s China might even have a naval base in Singapore. Impossible? Just look around your neighbours for the Chinese presence. Even countries like the Pacific islands (Fiji, etc) and East Timor are teeming with Chinese investments and Chinese people. How about Singapore? Don't you have more Chinese new arrivals than ever before? If you want your economy to boom, all you need to do is to welcome more Chinese-people, investments, and of course better IQ.
