I haven't seen a black american hired in tech in a decade. The last black american I saw in tech, they hired an indian manager, and the black guy was the first guy he fired.
Since then the only black guy I saw hired turned out to be from a suburb in africa.
My experience is the beneficiaries are people with well off parents from other countries.
Or white women.
There are two separate questions:
Do any individuals who are 'black Americans' benefit from AA - assuming for a moment that AA is a net benefit to the individual who gets it.
More importantly, is AA good for blacks in general, because as justification is cited that blacks lag behind other groups.
The former must be true, although they disproportionately do not benefit. It is mostly immigrants from West India and Africa who benefit, because they do much better than native American blacks, and AA is a benefit to people at the top of the group.
The second question is easier to answer: absolutely not. A very small group of middle- and upper class blacks get sinecures at the expense of whites and Asians. This at the cost of blacks everywhere being the bottom of the stack. If there is a 1 black who qualifies for a given MIT class, but they admit 10, the difference is that it is not one black who is just as good as the others, but at least nine who are incompetent. The worst performers will be the blacks. And obviously, they're not going to attribute the pride of their life, MIT admission, to their skin color, they will claim they had to work twice as hard to get where they are. Their poor performance they will have to blame on 'racism'. It's a disaster all-around.
It's not doing anything to promote income quartile transitions. The thing that they always claim to want.
