A few thoughs:
Opinions on "affirmative action" are meaningless without a specific delineation of what is meant. AA can mean anything from strict, enforceable quotas to just ensuring that people in the targeted group are considered for whatever benefit is being conferred (admission to a school or program, a job, etc).
Compulsory AA is not appropriate for the pure private sector. Government is not God and if I own a business then it must be my right to employ and promote whomever I want, based on whatever criteria are most meaningful to me.
A "viable" AA program sets a target of achievement and establishes a process, developed in good faith, that is intended to achieve that target. If the computer engineering department of MIT wants African American males to hold down 6% of their faculty positions IN THE FUTURE, they can set up a plan that does that. It might take 4 generations to achieve success, but they could have a plan.
A "viable" AA program ensures that nobody gets the "carrot" who is not fully qualified. The Ferguson, MO police department can't just start going out and hiring black people for the force. Police officers have to be intelligent and articulate enough to write a coherent arrest report, to testify at trial, to read and understand changing principles of constitutional law, and to conduct themselves accordingly. So an uneducated, reformed gang-banger from the Hood just won't cut it.
As painful as it is, American Black people have to acknowlege the unpleasant fact that all around them there are people who are the victims of serious discrimination and are succeeding educationally, economically, and socially, through hard work and sacrifice. We have jews, Koreans, Indians, Pakistanis, Chinese, and even black-skinned people from Africa who are making a killing in spite of being the victim of racism and other forms of bigotry. So to suppose that they only way Black people can prevail is through some sort of government assistance is B.S.
Indeed, it is self-limiting B.S.
