> The argument is that lack of privilege causes poor SAT scores which is preventing certain minorities from realizing their potential, and that this justifies selectively lowering the bar and allocating additional resources.

The UC system also removed SAT recently arguing it discriminates.

I haven't seen clear evidence though that the SAT discriminates more against poorer students than any other admissions factor. In fact given that richer kids go to elite colleges at higher rates than middle income, conditioned on same test score, I'm inclined to think it's being underweighted.
