China, critics will point out, doesn't produce (at least not yet) many Nobel Prize winners. But don't think the basic educational competence of the workforce isn't a key factor in its having become the manufacturing workshop of the world. It isn't just about cheap labor; it's about smart labor. "Whether it's line workers or engineers, we're finding the candlepower of our employees here as good as or better than anywhere in the world," says Nick Reilly, a top executive at General Motors in Shanghai. "It all starts with the emphasis families put on the importance of education. That puts pressure on the government to deliver a decent system."

And the Chinese government responds to that pressure in some intriguing ways. It insists that primary-school teachers in math and science have degrees in those subjects. (Less than half of eighth-grade math teachers in the U.S. majored in math.) There is a "master teacher" program nationwide that provides mentoring for younger teachers. Zhang Dianzhou, a professor emeritus of mathematics at East China Normal University in Shanghai who co-chaired a committee charged with redesigning high school mathematics programs across the country, says recent changes have begun to reflect more of a "real-world emphasis." Computer-science courses, for example, have been integrated into the math curriculum for high school students. And China is placing even more importance on teaching young students English and other foreign languages. If you think China's willingness to constantly fine-tune its educational system is not going to have much of an impact 20 years from now, there's a 7-year-old boy in Shanghai who'd be happy to discuss the issue with you. In English.

3. Look After the Elderly
it's hard to imagine two societies that deal with their elderly as differently as the U.S. and China. And I can vouch for that firsthand. My wife Junling is a Shanghai native, and last month for the first time we visited my father at a nursing home in the U.S. She was shaken by the experience and later told me, "You know, in China, it's a great shame to put a parent into a nursing home." In China the social contract has been straightforward for centuries: parents raise children; then the children care for the parents as they reach their dotage. When, for example, real estate developer Jiang Xiao Li and his wife recently bought a new, larger apartment in Shanghai, they did so in part because they know that in a few years, his parents will move in with them. Jiang's parents will help take care of Jiang's daughter, and as they age, Jiang and his wife will help take care of them. As China slowly develops a better-funded and more reliable social-security system for retirees — which it has begun — the economic necessity of generations living together will diminish a bit. But no one believes that as China gets richer, the cultural norm will shift too significantly.

To a degree, of course, three generations living under one roof has long happened in the U.S., but in the 20th century, America became a particularly mobile and rootless society. It is hard to care for one's parents when they live three time zones away.

Home care for the elderly will most likely make a comeback in the U.S. out of sheer economic necessity, however. The number of elderly Americans will soar from 38.6 million in 2007 to 71.5 million in 2030. But, says Arnold Eppel, who recently retired as head of the department of aging in Baltimore County, Maryland, "There won't be enough spots for them" in the country's overwhelmed nursing-home system. Appreciating the magnitude of the coming crisis, the U.S. government has begun to respond. Two new initiatives — Nursing Home Diversion and Money Follows the Person — expand subsidies for home elder care, and the Veterans Health Administration has just put in effect its own similar initiative. "The whole trend will be into home care, because nursing homes are too expensive," Eppel says, noting that nursing-home care in the U.S. costs about $85,000 annually per resident.

In China, senior-care costs are, for the most part, borne by families. For millions of poor Chinese, that's a burden as well as a responsibility, and it unquestionably skews both spending and saving patterns in ways that China needs to change (see Save More, below). For middle-class and rich Chinese, those costs are a more manageable responsibility but one that nonetheless ripples through their economic decision-making. Still, there are benefits that balance the financial hardship: grandparents tutor young children while Mom and Dad work; they acculturate the youngest generation to the values of family and nation; they provide a sense of cultural continuity that helps bind a society. China needs to make obvious changes to its elder-care system as it becomes a wealthier society, but as millions of U.S. families make the brutal decision about whether to send aging parents into nursing homes, a bigger dose of the Chinese ethos may well be returning to America.
