Ralph Richard Banks, a black Stanford Law professor, suggests in the WSJ in "An Interracial Fix for Black Marriage" that
Black women confront the worst relationship market of any group because of economic and cultural forces that are not of their own making; and they have needlessly worsened their situation by limiting themselves to black men. I also arrived at a startling conclusion: Black women can best promote black marriage by opening themselves to relationships with men of other races.
In the half decade or so after my 1997 article Is Love Colorblind, in which I sort of made a similar suggestion, I received lots of long emails from black ladies discussing these topics. From what I learned from these missives, I would predict that this isn't going to happen because, overall, black girls like black guys. A lot.
