Widening the pool, I suppose he means. Which brings to mind a recent vow by University of Colorado's Chancellor Richard Byyny. His proposed rectification is what he calls affirmative action. To him equal opportunity is confused with equal results. For the Chancellor they apparently do.
Equal results is the end which justifies unfair means.
Unfair to those faculty, staff, and students who happen not to be of the right gender, race, ethnicity, or origin. As to national origin, a rich Argentinean gets preferred over a poor white non-Hispanic male American. They argue that so long as the minority-member who gets the job is qualified, then he or she should be hired. Pardon me, but equal opportunity means that the best qualified candidate should be hired. If a majority member and another a minority were, as honestly as I could determine, equal in merit, I voted for the minority member.
