And as the field of bioethics has professionalized and diversified, questions have arisen about its direction and focus. Notwithstanding its early attention to instances of exploitation and abuse, some critics have discerned an increasing conservatism in bioethics that neglects the concerns of marginalized groups. These critics argue that with institutionalization, bioethics is losing sight of its radical origins (Holmes 1999; Purdy 2001; Eckenwiler and Cohn 2007). Bioethicists are tending to frame issues and formulate theory from the vantage point of privileged social and professional groups, even in the developing regions of the world as local bioethicists there seek a share in the prestige of high technology medicine (Salles and Bertomeu 2002; Luna 2006). During the 1980s, feminists in particular argued that bioethics was developing in a way that gave too little attention to gender-specific disparities in healthcare research and therapy, or to the effects of other power disparities, such as class and ethnicity, on quality of healthcare.
