The big surprise in the study was that Asians had to score significantly higher than whites, as well as blacks and Hispanics. Despite having a higher average SAT score, Asians have lower odds of admission than do "comparable whites."
Take away those inequities and Asian enrollment would do what it did at Caltech in California, where racial preferences are outlawed. In 1992, Asian enrollment was 25%. In 2013, it was 43%. According to Students for Fair Admission, an anti-affirmative action group, during the same period, Asian enrollment at Harvard, a staunch practitioner of affirmative action, went slightly downward, from 19% to 18%.
Liberals can't absorb the Asian factor. It doesn't fit the whites vs. people of color setup. What is most frustrating to liberals is that advocates can't point to Asians as victimizers of blacks and Hispanics to justify the unequal treatment. The old argument of compensation-for-past-abuses doesn't apply to them, only to whites.
