Fortunately he wont be around, because it will still take a number of years for China not to need the West buying their stuff and their high tech will still take some time to overtake the West.
It's a bit like the U.S in the old days, the Indians had a lot more people, but the whites had guns.
But that wont last forever, the West will become more and more reliant on China for manufactured goods, but as India, Thailand etc become more affluent, China will become less dependent on the West buying their stuff.
Then the West's buying power and currency values deminish.
It ain't rocket science, we have a trillion dollars debt and run a budget deficits.
How long does that run for, before someone says, " hey mate, your money's worth $hit". Lol
