It was never "supposed to fail". If you actually knew ANYTHING at all about military flight training; you would realize how utterly absurd that perverse fantasy is. Had IP's/instructor-pilots/flight-examiners been given ANY directive to eliminate those men from training; it would easily have been accomplished. Trust me on at least that much. No one goes all the way through to their Wings without scrooching up a bit along the way. One has to look at the student as a whole, and not just the mistakes. Flight evaluations are almost entirely subjective, in that there's one man/person/whatever only along with the undergraduate student...and guess what? Those that were then in the military as instructors-evaluators were evil white males! Go figure. That largely black, civilian Americans were contracted to instruct does nothing to limit what the white officer pilots could have done, had they chosen to, much less have been directed to do. That some students were subjected to unfair scrutinizing and ejection from training, I don't doubt, since it did sometimes happen. That there was often little love to be lost, I don't doubt, but the program most certainly wasn't "supposed to fail", or it would have, and early on at that, and long before combat was even an issue.
