The analogy also assumes the American produces nothing. He is simply endowed with his wealth (the tree). In reality, as I said above, the American's output is growing at about 3-3.5% every year -- less than the Asians', but still at a respectable pace.
You would also have to take into account the American's (and, if we chose to add him, the European's) incredible advantage in human capital -- an advantge that is slowly declining, yes, but no less still there.
That's not to say this all isn't a problem. It is, as people in America's Mid-West, England's North, and Scotland (along with many others in areas of Europe and America) can tell you.
Eventually, China is going to let its currency float, and the sooner it does so, the better, as far as I'm concerned. Will it be a tough adjustmen period? Perhaps. But perhaps not. Economics is not an exact science -- and I'm thankful for that, since it's impossible to divorce the field from politics -- and no one knows how the adjustment is going to hit.
