the rate of illegitimacy among Negroes is about fourteen or fifteen times that among whites. . . . Broken homes and illegitimacy do not necessarily mean poor upbringing and emotional problems. But they mean it more often when the mother is forced to work, . . . when the father is incapable of contributing to support, . . . when fathers and mothers refuse to accept responsibility for and resent their children, as Negro parents, overwhelmed by difficulties, so often do. . . .All this cannot be irrelevant to the academic performance of Negro children, and indeed it is relevant to a much wider range of problems than educational ones alone. In particular, it is probably the Negro boy who suffers in this situation. . . . It is pointless to ignore the fact that the concentration of problems in the Negro community is exceptional, and that prejudice, low income, poor education explain only so much.
