Here the one to a study that was able to give a nice hard number to HOW MUCH discrimination is found in Ivy League college admissions.
NOrmally I would like to link to a report about the article, to make it more readable, BUT all the ones I find that are NOT found conservative sites, seem solely concerned with the impact on Asians, without reference to whites.

"Based on complete data for three applicant cohorts to three of the most academically selective research universities, we show that admission bonuses for athletes and legacies rival, and sometimes even exceed, the size of preferences for underrepresented minority applicants.
Being African American instead of white is worth an average of 230 additional SAT points on a 1600-point scale, but recruited athletes reap an advantage equivalent to 200 SAT points.
Other things equal, Hispanic applicants gain the equivalent of 185 points, which is only slightly more than the legacy advantage, which is worth 160 points.
Coming from an Asian background, however, is comparable to the loss of 50 SAT points. As sizeable as these preferences are, we provide evidence that their magnitudes are biased down by relying on SAT scores as the sole indicator of academic merit. When such additional measures as high school GPA and class rank are included, being a recruited athlete has an even greater impact on one’s chances of admission. The African-American and Hispanic advantage also increases, as does the disadvantage if one has an Asian background."
