Corporations and colleges are still biased against race, because the demographics of corporations do not reflect the population as a whole, and if they were hiring correctly, they would.
On other words - if 20% of the general population of 300 million people is a certain race, it stands to reason that corporations and colleges should mirror that. But they do not. The applicant ration is the same, but the actual hiring ratio is much, much smaller. Where do work? In an office? Stand up and look around and tell me if 20% of your coworkers are black. It should be pretty close.
It isn't.
No engineer or mathematician would argue this - if everyone hired entirely based on qualifications your workforce would directly represent the population at large.
Law of averages in a perfectly unbiased hiring world would make this so.
