People certainly have a bias towards those-like-me, but it's not specifically anti-black, it's against anyone who looks/feels/smells different.
It's debatable whether or not it's specifically anti-black. Or anti-some-other-group. At any rate, a bias against those-not-like-me would be sufficient in this case to cause blacks a significant deficit in opportunity for employment in a historically majority white nation.
Um, the IQ would be different?...
As usual, I phrased my comment poorly. Let me try a different tack...
You are saying black Americans have a genetic deficit in the form of lower average IQ. Because IQ is heritable and very important toward social "success", this is a (or even the?) major factor in why they lag behind in certain social metrics (avg. income/wealth, crime rates, etc.) in American society.
I'm saying slavery/segregation/discrimination has created a very significant deficit for blacks to overcome in America, to the extent that we would expect to see something like we see in terms of the disparity in avg. income/wealth, crime rates, etc. I'd hypothesize slavery/segregation/discrimination has been consequential to the extent that even if blacks had a higher average IQ than whites, they would still be in a similar situation. (i.e. the discrimination is that bad and that significant.)
Plainly, advanced IQ (or other genetic advantages) aren't enough to overcome significant discrimination in all cases. The disadvantages can be too steep in a given society.
I'd propose a good portion of the U.S. is a bit more racist than I think you are taking into consideration. And this may have caused a deeper deficit for blacks than you are appreciating.
As to similarities, I was about to write that the discriminated-against will never rise to the highest positions in the society, but oh look! there is that Barack Hussain fellow...
Things can change. Slowly.

Will it? I agree that it will cause some harm, but I'm not sure about "significant". Note that race-based discrimination is explicitly illegal and agencies such as EEOC do prosecute. Moreover, EEOC uses the concept of "disparate impact" which basically means that if you statistically discriminate regardless of your intent, you are in trouble.
Also, did a bias agai...
If it's worth saying, but not worth its own post, then it goes here.
