<p>newjack, under-represented racial/ethnic groups, not based on economics, you originally used lower middle class, now you are backing off, disingenuous of you. Anti-discrimination laws on the other hand prohibit discrimination on basis of race, gender, religion, sex, national origin, etc. AA applies to under-represented racial/ethnic groups but a university may deem lower middle class as under-represented in their student body and strive to recruit them, that is not AA. You need to know the subtle difference involved.</p>
