You might be right that there is no way to completely scrub out race. But an ID system is still so much better. Not all applicants -- and my guess is most -- have work related to an organization with ethnic links. Asians who wish to avoid being discriminated based on their ethnicity can always avoid writing about their race in the personal essays. I have seen many other students' essays and actually not many do allude to their ethnic group. And lastly for the phone interview, I don't believe it's a big problem as the accents of most 2nd-3rd gen Asian-American students aren't all that different from the average middle class white student contrary to popular stereotypes.
