I really do not believe that supporters of reparations can expect some kind of cash deal.  Others have explained the complications better than me; what if you are an immigrant after date X; should descendants of Union soldiers get discount, etc.  Unworkable.  The real goal is a pile of money ($500 million should do) and control of the board of directors to dispense the money as they see fit, eg, support education, employment training, *influencing power*, etc.
