Affirmative Action is to care for minorities, aren't Asian Americans minorities in this country? What's the definition of Minority in US? Why are so many blacks in NBA? The best solution is to set up a few Asia-American self-funded private schools across the country, where academics becomes the major admission criteria and your race does not matter, of course this has to be stated carefully otherwise you still could be sued for "discrimination" becomes some group of people will be least represented as expected. Affirmative Action will not make those who can take advantage strong, as strong comes from serious competition only, they will make that group stay weak for good. It's simply unfair to those kids who spent most of their time learning, what a shame to Harvard and the Supreme Court.
