Quote from trefoil:
Per capita is obviously not the same as the gross sum. Obviously.
And, all your article asserts is another obvious thing: PPP is an approximation. As is exchange rate parity, of course. However, if you have a currency that has been deliberately manipulated to an absurdly low level, as is the case with the remnimbi/yuan, then using PPP is going to be a much closer approximation of reality than using exchange rate parity. .
PPP comparisons are meaningless for these 'king-of-the-hill' type debates.
Y? Because the deciding factor is military power.
US military technology is at least 3 generations ahead of PRC.
For China to play keep up, advanced military hardware must be imported --- priced in USD or EURO.
So the parity conversion goes right out the window since all definitions of parity are comparisons relative to cheap production at HOME.
When the YUAN goes abroad to buy goods, fogetaboutit.
Second. Exchange rate parity is the most accurate GDP measure (for China).
Granted, its rigged by an easy 30%.
But what makes anyone think the world economy would continue tickety-poo if China let the Yuan float?
The net effect would be akin to China dumping US Treasuries and the US dollar (and economy) would tank.
Empty wallets for Chinas' most loyal customer is bad news for the Reds.
Whats keeping this money pump boom afloat is cheap Chinese goods. Once thats gone, this 'recovery' is done. Thats basic economics right there.
