Over the past twenty years, the United States has suffered an oddly unfavorable position in the global economy. China has been wealthy enough to bid up resource prices, including oil, but not wealthy enough to buy enough major American exports to bring buying and selling into even rough balance. Nor has China been innovative enough to come up with new products for American consumers. As China continues to grow, America will become a bigger winner. Just as Canada and Australia have prospered over the past ten years because their specialties matched Chinese demands, the United States is likely to be the bigger winner in the next ten years as Chinese (and other) demands mature.
