That said, I'm mostly just speculating based on studies in other areas that have found equal discrimination. For example, black cops discriminate against black suspects just as much as white cops do. I don't know of an employment discrimination study that addresses that question.
I still think you are wrong though. I think you will find that a majority of minority owned businesses hire far more within their race. And thats not a BAD thing.
Heres another observation...I was in Chicago recently...damn near every store in downtown Chicago was manned by immigrant employees. Why do you suppose that is? (not laying a trap...I'll tell you my thoughts...it is because employer experience has shown that immigrants are willing to bust their ass, do a good job, because they value the job more than a typical American apllicant).
