Why would a company be forced to promote someone that is less experienced and less of an overall asset because of skin color? What are you are doing is assuming that everyone that maybe got in because of AA has less experienced and is less of an overall asset. So because they are not white we must automatically assume they are not as a good of a worker.
Or we can not be ignorant and use an example were both people are both good workers and the only difference is race.
As for your article the girl is suing on the belief that she was not chosen because she was white. Not because she found out she was but that she has the belief that her qualification are better than most of the non-whites that are in the school.
And while they do use AA for the most part they what sounds like a fair plan.
The school uses a "Top 10 Percent" plan, through which students in the top 10% of their high school graduating classes are automatically admitted to the state university of their choice. That has helped schools boost racial diversity, primarily because most of the state's public high schools are segregated by race and ethnicity.
