In a thorough and important, if often tiresomely repetitive, study, Solinger (Women's Studies/Univ. of Colorado, Boulder) dissects the politics of female fertility in America from 1945-65, when the strikingly different treatments of middle-class white and poor black pregnant teenagers clearly reflected the demands of a racist, family-centered economy. Before WW II, Solinger reports, unwed mothers in the US were considered the products of defective, amoral environments-- permanent outcasts for whom no kind of rehabilitation was possible. After the war, she argues, a perceived societal need to produce as many white children in ``healthy'' male-headed families as possible, combined with new Freudian psychological theories and racist sociological assumptions concerning black sexuality, engendered a dualistic treatment of unwed pregnant women depending on the color of their skin. Whereas the ``market value'' of white babies enabled and even encouraged white single mothers to ``sacrifice'' their offspring for adoption in exchange for a second chance at respectability (usually after exile in a maternity home), ``unmarketable'' illegitimate black babies were considered the inevitable product of the ``natural'' black libido and were therefore left to be raised by their mothers, who were in turn treated as incorrigible breeders who gave birth to win more government benefits. With the ``sexual revolution'' (for whites) and ``population bomb'' (for blacks) of the late 60's and early 70's came the technological fixes of birth control and legalized abortion--though these steps toward female self-determination for women of all races were more a result, Solinger claims, of a slump in the white baby market and fear of black overpopulation than of societal concern for the fate of single mothers. Revelatory but regrettably dry work with repercussions for today.
