I hope you realize your mindset is what caused the most recent (and ongoing) recession - "the sub-prime mortgage credits" granted to people, who were clearly classified as a high-risk group that would cause severe losses on the average due to failure to pay them - but since they happened to be covered by anti-discrimination laws, the credits had to be granted anyway.
That's when political correctness trumps plain business sense and plain scum can get privleged treatment simply based on their skin color.
The blacks, instead of trying to force more acceptance through laws, should first get to cleaning up their own backyard and simply reduce the reasons that acceptance is so hard to come by: glorification of violence and crime, the "I deserve, you owe me" attitudes, poor ethics, and above all ostracization of these of their society, who grew successful through honest means and education.
Unfortunately, all these anti-social behaviors are ingrained as their "culture" and defended fiercely; they form a self-destructive society and then they resist if the destruction of their society spills out and is fought back.
And these, who broke out of the trap, suffer mistrust and discrimination simply because they are still suspect to be "wolves in sheep skins". And the prevalent belief that they are unable to fail on their own - that all their failures are a result of discrimination - really doesn't help things.
Imagine a situation: There are two black girls that join the college. One studies, works hard and passes all the exams just fine; not brilliantly but well on par with other good students. The other doesn't. She hangs out with the low-life, she choose the life of parties and drinking. When exam time comes, she fails along with fellow white party animals, but unlike them, she submits a complaint that she was discriminated against, and threatens the school with lawsuit. The school yields and grants her the diploma.
The two show up for a job interview. They have the same diplomas. The employer knows about their skill only basing on their diplomas (needs an expert in a field he's a layman in) and has a good clue about practices of extortion of such diplomas. He may choose either of them, or a white graduate who didn't have the leverage of discrimination lawsuit. He has a good business sense, and picks the low-risk white.
It's the "few rotten apples" problem, except the rotten apples are quite numerous and any attempt to "un-rot" them is touted an assault on the black culture.
