The problem with these perceptions – both at home and abroad – is that the US remains the world’s most powerful country, and is likely to remain so for decades. China’s size and rapid economic growth will almost certainly increase its relative strength vis-à-vis the US.
这些感觉（不论在国内还是在国外）的问题在于美国仍是世界最强大的国家，并且可能在未来几十年中都是如此。中国的规模和快速经济增长几乎必然会增加它相对于美国的优势。但即使中国在未来几年中成为世界最大经济体，其人均收入要想超过美国还需要几十年之久。
