I heard an interesting fact on China - apparently they grew something like 14% for a year around 10 years ago - and let's say they grow just 4% this year. Here's the thing: Because the chinese economy is so much larger now, the 4% from this year added more to the world economy than the 14% 10 years ago.
Which puts some of their slowdown into perspective, no?
(I may have the 14% number wrong, but you get the point)
This is similar to the fascinating fact that apparently there are more 20-29s in the US than the 10 peak years of baby boomers - because the country is so much larger now. But no one thinks that - we all think there is this giant lump of baby boomers outweighing the rest of the age groupers.
(and yes, the chinese stock market is still 38% higher now than a year ago)
