A new report by the Congressoinal Black Caucus raises concerns that a number of committees, chaired by whites, have far too few black staffers and aides serving on them. I have no reason to doubt the CBC's numbers, but I strongly disagree with how problematic that is.
Besides drawing on seasoned veterans (yes, not every congressional staffer is a rich college intern), most committee chairs use their privileged position to reward their home constituencies. Meaning, their committees tend to reflect their home districts. Committees chaired by blacks have more black staffers because their district is black. You really wouldn't expect an Agriculture committee or its subcommittees, which are manly populated by Plains state legislators that represent states and districts that are upwards of 90% white to have large numbers of minorities.
Does it affect policy? Yes. But, so does not having strict gender parity too.
A better strategy to achieving real parity is for the CBC to continue focusing its efforts on helping African Americans get through this terrible recession in one piece.
