Agreed, NickG, but there are many other factors to consider besides just race when it comes to diversity.
It's a shame that colleges can't have a face-to-face interview with each and every applicant...I feel that's the only way to truly get a good grasp of someone's character, and of what they'll bring to the organization. People can't be judged fairly by anything other than honest in-person interaction.
Of course, and we should have class-based affirmative action as well. In fact, I would support exclusively class-based AA if it was guaranteed to achieve a "critical mass" of diversity on other axes, like race. But I'm not convinced that it is.
