It's very interesting to note where the debate about diversity is taking place. It is taking place primarily in political circles. Here at the College Fund ,we have a lot of contact with top corporate leaders none of them is talking about getting rid of those instruments that produce diversity. In fact, they say that if their companies are to compete in the global village and in the global market place, diversity is an imperative. They also say that the need for talented, skilled Americans means we have to expand the pool means promoting policies that help provide skills to more minorities, more women and more immigrants. Corporate leaders know that if that doesn't occur in our society, they will not have the engineers, the scientist, the lawyers, or the business managers they will need. Likewise, I don't hear people in the academy saying. 'Let's go backward. Let's go back to the good old days ,when we had a meritocracy (不拘一格选人才)' ( which was never true-we never had a meritocracy, although we've come close to it in the last 30 years ). I recently visited a great little college in New York where the campus had doubled its minority population in file last six years. I talked with an African American who has been a professor there for a long time, and she remembers that when she first joined the community, there were fewer than a handful of minorities on campus. Now, all of us feel the university is better because of the diversity. So where we hear this debate is primarily in political circles and in the media-not in corporate board rooms or on college campuses. The word' imperative'( Para. 1 )most probably refers to something ______.
