A. Convincing evidence: US is losing its appeal in the eyes of multinationalsB. Biggest hindrance: US divided political systemC. American future: stuck in the middleD. Overstated statement: US overall competitiveness is decliningE. Voice of experts: pessimism pervades academic worldF. Economic outlook: bad but not desperateG. Undisputed fact: US is losing its economic edge 1 Is America fading America has been gripped by worries about decline before, notably in the 1970s, only to roar back. But this time it may be serious. There is little doubt that other countries are catching up. Between 1999 and 2009 America"s share of world exports fell in almost every industry: by 36 percentage points in aerospace, nine in information technology, eight in communications equipment and three in cars. Private-sector job growth has slowed dramatically, and come to a halt in industries that are exposed to global competition. Median annual income grew by an anemic 2% between 1990 and 2010. 2 The March issue of the Harvard Business Review is devoted to "American competitiveness". The Review reports that declinism is prevalent among HBS alumni: in a survey, 71% said that American competitiveness would decline in the coming years. 3 America is losing out in the race to attract good jobs. Matthew Slaughter of Dartmouth"s Tuck School of Business points out that multinational firms increased employment in America by 24% in the 1990s. But since then they have been cutting back on jobs in America. They have moved dull repetitive tasks abroad, and even some sophisticated ones, too. The proportion of the employees of American multinationals who work for subsidiaries abroad rose from 21.4% in 1989 to 32.3% in 2009. The share of research-and-development spending going to foreign subsidiaries rose from 9% in 1989 to 15.6% in 2009; that of capital investment rose from 21.8% in 1999 to 29.6% in 2009. 4 America"s political system comes in for particularly harsh criticism: 60% of HBS alumni said that it was worse than those in other advanced countries. David Moss of HBS argues that such complaints are nothing new: American politicians have been arguing about the role of government ever since Thomas Jefferson butted heads with Alexander Hamilton. But in the past this often led to fruitful compromises. But such compromises are rarer these days. Republicans and Democrats are more ideologically divided, and less inclined to make pragmatic concessions. 5 For all this gloom, the Review"s gurus argue that, as Bill Clinton said in his first inaugural address, there is nothing wrong with America that cannot be cured by what is right with America. The country has huge strengths, from its world-beating universities to its tolerance of risk-taking. It has a highly diverse market: firms that seek cheap labour can move to Mississippi, where wages are a third lower than those in Massachusetts. Rosabeth Moss Kanter of HBS points to the extraordinary amount of innovation that is going on not just in Silicon Valley but across the country.Yet it is difficult to read this collection of essays without a sense of foreboding. The one thing that worries the HBS alumni more than anything else—the state of American politics—is the most difficult to fix. The politicalsituation swings unpredictably, making it hard to plan for the future. Should companies assume that they will have to abide by Mr. Obanm"s health-care law when it comes into effect in 2014, or will the Republicans have repealed it by then No one knows.

The Carnegie Foundation report says that many colleges have tried to be "all things to all people". In doing so, they have increasingly catered to a narrow-minded careerism while failing to cultivate a global vision among their students. The current crisis, it contends, does not derive from a legitimate desire to put learning to productive ends. The problem is that in too many academic fields, the work has no context; skills, rather than being means, have become ends. Students are offered a variety of options and allowed to pick their way to a degree. In short, driven by careerism, "the national colleges and universities are more successful in providing credentials than in providing a quality education for their students." The report concludes that the special challenge confronting the undergraduate college is one of shaping an "integrated core" of common learning. Such a core would introduce students "to essential knowledge, to connections across the disciplines, and in the end, to application of knowledge to life beyond the campus". Although the key to a good college is a high-quality faculty, the Carnegie study found that most colleges do very little to encourage good teaching. In fact, they do much to undermine it. As one professor observed: "Teaching is important, we are told, and yet faculty know that research and publication matter most." Not surprisingly, over the last twenty years colleges and universities have failed to graduate half of their four-year degree candidates. Faculty members who dedicate themselves to teaching soon discover that they will not be granted tenure, promotion, or substantial salary increases. Yet 70 percent of all faculty say their interests lie among more in teaching than in research. Additionally, a frequent complaint among young scholars is that "There is pressure to publish, although there is virtually no interest among administrators or colleagues in the content of the publications."
A．ignores the actual situationB．is not based on the right perspectiveC．0nly focuses on an integrated core of common learningD．gives priority to the cultivation of a global vision among students
