Those who argue that America is in decline&#160;have a difficult case to make in economic terms. For all its recent woes (which many countries would gladly exchange for their own), the US remains a dynamo of industry and innovation, and may be emerging as an energy powerhouse as well.
那些认为美国正在走向衰落的人很难从经济角度解释自己的说法。美国最近的确遇上了困难（对许多国家来说这算不上什么困难），但仍然是工业和革新的火车头，而且很有可能在未来崛起成为一个能源大国。
