This is precisely why the labor struggle needs to be all inclussive. We instinctively identify with people who are most like ourselves or who can best understand our struggles. If the working class is more unified all of the sudden the white worker might realize that he has a lot more in common with the black person next to them (struggling in the same way to pay mortage, health care, tuition) than the white person who is mananging the operation. It seems a unified class struggle will foster more understanding between the races than government programs ever could (and let it be known that I believe that government programs not only have a place but are necessary in fostering more equality). And you are right, this would not directly speak to the plight of blacks. But it seems that the result could be less deaf ears.
