As you assert, dysfunctional public education indeed oppresses blacks and all others who must endure it. However, good education is not a monopoly of the public school system.
Never has knowledge been so freely available but so seldom accessed. Today a good education, as opposed to Gate’s meaningless credentials, is a matter of desire, discipline, and diligence. And those are of the individual, not the institution.
While everyone would prefer a private education (or homeschooling), it often isn’t practical. The oppression from public education doesn’t just come in the form of teaching very little; it is the blatant dishonesty with grades and the criminal racket of the teachers’ unions (which locks the dysfunction in place).
One issue I see in the workplace (which drives a lot of racial paranoia for blacks) is that when they have the same credentials as others (though they didn’t earn them/learn to obtain them), they can’t understand why advancement doesn’t follow. I have a co-worker with a masters degree in a business field, and he can’t write an intelligible email or balance a checkbook; he briefly left for a higher position elsewhere, and lost the job when the truth surfaced about his abilities versus what he could do “on paper”. He is back in the more entry-level position he left, very frustrated, and is now a full-fledged racial conspiracy theorist.
Simply giving people unearned diplomas, degrees, jobs and promotions is simply deferring the riot until they are a little older.
