Billy T, I don't think China nor Australia's economies are balanced.
I agree but as an economy union they are.
I have long stated that the fate of Brazil, Canada & Australia, etc. - the raw materials, energy, & food suppliers to Asian (especially China) is to be come "economic colonies" of China. They will import China's high value added products and pay for it with their low value added exports. The low valued manufactured shirts, shoes, plastic junk toys, etc. these colonies import will come from low labor cost Asian countries - Certainly not China any more as it already has labor shortage and resulting rapidly (>10% real purchasing power / year) rising labor costs.
The US and EU will be relatively unimportant economical in global trade as they will be in deep, long-lasting, depression soon. (China is tired of trading mainly with countries that need loans to buy and is rapidly growing it exports to these suppliers and other Asian countries who manufacture the simple components, like fans China builds into a car or its high value added electronic exports. Chinese exports to the 8 countries of SEATA were up 37% in 2010! When this intra-Asian trade and domestic demand plus the development of infrastructure in Africa, up 14% in last few years, fully occupy China's factories, they will tell the "borrow to buy" US & EU to go to Hell and say: "We don't finance the deficits of dead beats any more.")
China invested massively into factories to make cheap shit for Europeans and Americans and have built a massive property bubble and a number of ghost cities (not towns, cities). People who live off the land can not be expected to *poof* suddenly be happy getting up at 6am and working till 9pm to return to a small box of an apartment over night AND those buildings will begin deteriorating day lot. You really need someone there to take care of them.
Australia also has a huge property bubble, some say 40% over prices and is more highly leveraged than the USA. If shit takes a tumble in the USA, AU will probably fall flat on its face. Not to mention the economy is massively skewed to favor resources. Lots of jobs in mining, not to many in IT. Then there's the baby boomers. ...
Many of the "junk toy" factories along China's coast have closed or have been converted to supply the growing domestic demand, but this is just beginning. Yes there are problems with converting former pig farmers into urbanities - For example, the older men still piss in the streets. China is presiding over by far the greatest and most rapid mass urbanization in human history. Convert from a rural farm population to cities (100 new ones for 1 million population each, plus large expansion of the older cities in the interior.) in about a decade. That took the US > 50 years and involved many fewer people.
As far as the housing bubble in China & Australia is concerned first see my recent post, 222, replying to SAM and note that even with some falsely high data, the prices per square foot are a tiny fraction of those paid in Paris. I did not find any for Australia but Auckland NZ's averge cost is $450/sq. ft. In central Beijing, $400/ sq. ft. and for a “high end” apartment in Shanghai it is $500/ sq. ft. Compared to $3,287/ sq ft. in Paris!
Where did you say the housing bubble was?
