Examples of affirmative action

Say your white and are applying for an elite college. You have a 4.0 GPA and have worked hard all your life to get into this college, but there is only one spot available for the next semester. The other kid applying for the spot is say Black (or any other minority for that matter) with a 2.0 GPA. The school legally has to fill the quota and let in a certain amount of minorities no matter what their qualifications are. So if the quota isn't met that student is in and you're out. So you don't get to go to that school thanks to affirmative action.
