There are some scholarships available only to blacks, or women, or American Indians, or minority women, etc ... so these people pay less, on average, than white males do. In which case, the cookies should all cost the same, but with "scholarships" that amount to refunds if one is in an affirmative class.
While some scholarships may be available only to minority students, scholarships in general are not available exclusively to minorities. Some are based on race, some on need, others are based on merit, or given by the employer of a student's parent, or by community civic groups, or given to students with a specific talent.
Scholarships are money paid to a university/college for an education, not just a piece of paper with no value. A student may pay less, but the degree didn't cost any less.
Since merit isn't the determining factor in college admissions, I see this not as a 'some pay less, some pay more' issue, but as a 'count based on race' issue -- for each academically qualifying non-minority admission, there must be so many non-academically qualifying minority students admitted for a diverse student body.
Interestingly enough, I don't see colleges paying the same attention to diversity when hiring teaching staff. Quite a double standard there.
What I think is really, really sad about affirmative action is the general perception that a minority student can't merit a college admission so affirmative action is necessary. Why aren't we fixing our schools instead of admitting based on race *for diversity*.?
The effect? While not strictly minority student driven, I've seen courses dumbed down an entire class level; students expecting a pass for no other reason than they showed up for class; very creative grading to pass students with a C. All this, and much more, in the time it took high-school freshmen to become college freshmen.
