那些真正成功的例子，那些我们现在称为发达经济体的国家，都是高收入经济体，或者说是工业化经济体。那些国家只代表六分之一的人类。剩下六分之五的人类被我们称作发展中经济体。这是世界上极大的一部分。有些情况下两者之间的差距可以达到200：l，如果你简单地将美国的人

Passage One:
    It happens that the real success stories, those countries that we now call the developed economies, were the high-income economies or, the industrialized economies. Those countries represent only about one-sixth of humanity. And five-sixths of humanity is what we call the developing world. It’s the vast majority of the world. The gap can be two hundred to one in some cases if you simply measure the gross national product per person in the United States versus, say, a country in Africa, maybe a gap of $30,000 per person and $150 per person. That’s absolutely astounding, to be on the same planet and to have that extreme variation in material well-being.
Passage Two:
    Arms control, as part of an overall strategy of advancing American interests, remains a very high priority. Arms control can be an important part of American foreign policy, but I think the real question is what advances our national interests. And in those cases where, for example, arms control treaties are ineffective or counterproductive or obsolete, they shouldn’t be allowed to stand in the way of the development of our foreign policy. And I think that’s part of what we’re trying to articulate as we go through reviewing some existing treaty obligations and considering whether or not to get into potential new obligations as well.
