问题     It is a truth universally acknowledged that education is the key to economic success. Everyone knows that the jobs of the future will require ever higher levels of skill. That’s why, President Obama declared that "If we want more good news on the jobs front then we’ve got to make more investments in education. " But what everyone knows is wrong. The fact is that since 1990 or so the U. S. job market has been characterized not by a general rise in the demand for skill, but by "hollowing out": both high-wage and low-wage employment have grown rapidly, but medium-wage jobs — the kinds of jobs we count on to support a strong middle class — have lagged behind. And the hole in the middle has been getting wider; many of the high-wage occupations that grew rapidly in the 1990s have seen much slower growth recently, even as growth in low-wage employment has accelerated.
    Why is this happening? The belief that education is becoming ever more important rests on the plausible-sounding notion that advances in technology increase job opportunities for those who work with information. However, some economists argued that this was the wrong way to think about it. Computers, they pointed out, excel at routine tasks, "cognitive and manual tasks that can be accomplished by following explicit rules. " And here’s the thing: Most of the manual labor still being done in our economy seems to be of the kind that’s hard to automate. Meanwhile, quite a lot of white-collar work currently carried out by well-educated, relatively well-paid workers may soon be computerized.
    And then there’s globalization. Once, only manufacturing workers needed to worry about competition from overseas, but research by Alan Blinder and Alan Krueger suggests that high-wage jobs performed by highly educated workers are, if anything, more "offshorable" than jobs done by low-paid, less-educated workers. If they’re right, growing international trade in services will further hollow out the U, S. job market.
    So what does all this say about policy? Yes, we need to fix American education. In particular, the inequalities Americans face at the starting line — bright children from poor families are less likely to finish college than much less able children of the affluent -- aren’t just an outrage; they represent a huge waste of the nation’s human potential.
    But there are things education can’t do. In particular, the notion that putting more kids through college can restore the middle-class society we used to have is wishful thinking. So if we want a society of broadly shared prosperity, education isn’t the answer — we’ll have to go about building that society directly. We need to restore the bargaining power that labor has lost over the last 30 years, so that ordinary workers as well as superstars have the power to bargain for good wages. We need to guarantee the essentials, above all health care, to every citizen. We can’t just give workers college degrees, which may be no more than tickets to jobs that don’t exist or don’t pay middle-class wages.
The author holds in Paragraph 1 that the U. S. job market______.

选项 A、has justified the importance of education to economic success
B、has been characterized by a rise in demand for skilled workers
C、has seen unbalanced job growth among different wages

答案C

解析 第一段指出美国就业市场的显著特征:高薪就业和低薪就业迅速增长,而中等薪资就业增长已落后;且最近此趋势进一步加剧:曾经增长迅速的“中等薪资职位中的高端职位”也出现大幅下滑。由此可推知,美国各级薪资之间就业增长不平衡,[C]选项正确。
