Not the OP, but one example is that it may benefit the well-connected minorities rather than those with less opportunities. If the goal is to raise opportunity for a historically disenfranchised group, this may not meet the end goal. For example, imagine a hiring goal is to increase the number of minority X. This may give additional leverage to someone of that group who already comes from a well-connected family and already has the opportunity to obtain the necessary credentials. It does nothing to give the opportunity to those in a less privileged group obtain those credentials in the first place. It doesn't mean it's wholly bad policy, but it can lead to the pattern of pointing to those successful outcomes as evidence that we're in a post-racial era. And so even less focus is paid to those who actually need more opportunity.
