I really apologize for the off-topic, it will by my last post in this topic that doesn't include the words Japan, nuclear or tsunami, I swear!
For 200 years China did nothing
The same can be said for most countries.
The economic boom of the last two centuries started when the Age of Industrializiation hit. And it hit China a lot later than Europe or America. Once it did, China benifitted from all the advancements made. The leadership's smart politics is that they largely ignore the humanitarian and social progress made in Europe and America and implemented a Capitalism of the 19th century. You call that smart, other people might call it ruthless. Yes, it helps the country as a whole and future generations might benefit greatly from it. I just wouldn't want to live there now
This US imports more than it exports.
And the German economy exports more than it imports. Live's not a wishing well.
China will ultimately run into the same problems that other rich countries run into. They're not doing anything special. And believe you me, the US is not looking any better or worse than any EU country.
The only country that comes to mind that really does something special is Norway, who have had their federalized oil industry and they've been spreading the wealth from that among the people and they're now putting a lot of money into a huge federal fund for the time after the oil runs out.
