" Within the overall goal of social equality, greater minority representation in professions like law and medicine is desirable for several reasons. Members of minority groups are more likely to work among their own people than those who come from the mainstream ethnic groups, and this may help to overcome the scarcity of doctors and lawyers in poor neighbourhoods where most members of disadvantaged minorities live. They may also have a better understanding of the problems disadvantaged people face than any outsider would have. Minority and female doctors and lawyers can serve as role models to other members of minority groups and to women, breaking down the unconscious mental barriers against aspiring to such positions. Finally, the existence of a diverse student group will help members of the majority ethnic group to learn more about the attitudes of members of the minority group, and thus become better able, as doctors and lawyers, to serve the whole community.
