This is what bothers me the most. The thinking seems to be that by deliberately employing "positive" discrimination, someday we'll detect that bias has been eliminated, and then the government will instruct all institutions throughout the country to dismantle their discriminatory policies. Having deliberately practiced discrimination for 10, or 20, or 30, or however many years, someday we'll see it isn't needed anymore, and stop. To me, that's absurd.
For one, I doubt we'll ever detect that bias has been eliminated. Secondly, even if we did, we'll never dismantle the institutional policies of discrimination, because at that point, far too many people would be benefiting from them. We seem to be deliberately implementing institutional discrimination on the assumption that differences of outcome necessarily represent oppression.
