Edwards may have his statistics right, I don't know. The REASON for this disparity, I suspect, has to do with whether or not the family is intact, that is, is there a father AND a mother in the home. Just this one fact makes the biggest difference in the economic health of a family. Democrats always ignore this fact, and narrow the difference down to race.
I bet the average Indian-American family has more than $80,000 in assets, and their skin is just as dark as most blacks. The difference is that their families are strong and they value education.
