It matters because large numbers of people are denied opportunities based on discrimination. They can be denied by direct bias (e.g., 'we don't hire women because we think they are lousy engineers'; or 'women won't fit in our boys' club workplace') or indirect (e.g., discrimination causes more poverty for black families, and impoverished students perform poorly for a number of reasons; edit: or a student does not want to be the only woman/latino/black/etc. in every class for the next four years). It is unjust for the people discriminated against and bad for our society: Our workforce loses valuable talent, and, from what I've read, diversity in the workplace is widely believed to improve performance (due to a wider number of perspectives and experiences).
