Affirmative action will not even the field. Productive workers are found by hiring bright, capable and passionate humans. Social skills and effective decision making skills are essential to the entire process of interviewing and hiring. If we expect to live "as one nation under G-d" we need to focus on what we want in the work force and I believe that education is the key. Educating our youth to become capable and effective people will eliminate the need for any type of affirmative action.
Race should have no part of the decision making process, black, white, purple, or brown. It muddies the quality of education in the university, and it creates a separation between those who are accepted on merit and those selected on race. It is also counter-productive because it sets the bar low and doesn't allow minorities to truly be respected because they are perceived to have gotten a handout.
