The root cause of it is that blacks are incompatible to western civilization. When they can’t be extracted, the civilization has to be compromised. The outcome is affirmative action
That’s an oversimplification; the real problem with affirmative action is that it puts preferred minorities in slots (in both school and the workplace) beyond their abilities, instead of a position where they could do well. For example, the applicant who is qualified for community college is bumped up to the state school, and the applicant that is qualified for the state school is bumped up to the Ivy League - and in both cases they usually fail - as a white person also would - but are given “minority Cs” (as opposed to “gentleman’s Cs”) and pushed through. The same dynamic then flows through the workplace, and with the same result: failure, and another cover-up.
In the end, you have preferred minorities who assume racism is holding them back (because they have the same papers as their white & Asian co-workers), and you have companies forced to double costs while they continue paying a competent, qualified worker to get the job done. Race relations are strained further, and a toxic work environment is maintained.
In the end, it helps nobody; it re-distributes wealth at a disastrous cost to the recipient and those around him/her.
