This brings up a point that is often overlooked - the fact that a shocking number of major corporations are quite leftist in nature. The list of supporters of racial preferences who sided (and ultimately won) with the University of Michigan in the Grutter decision included many from the Fortune 500 in addition to the ususal suspects.
The MBAs being graduated from schools like Harvard receive the same thorough leftist indoctrination that other Harvard students do, and it takes root in a certain number of cases. Gramsci's model for socialism is well under way.
If corporations may legally and officially have reverse discrimination policies, then they are protected from discrimination lawsuits--no white male ever wins a discrimination lawsuit; however, if they cannot and do not have reverse discrimination policies (i.e., they hire on merit alone), they stand to be sued every day by some "victimized minority" who doesn't measure up. It's not all "social consciousness."
