 Still, the rectification of such structural discrimination may raise more difficult issues for people with disabilities than for women, because there is greater uncertainty and potential for disagreement about the extent of the changes that are required to treat people with disabilities as social and political equals. Indeed, the range and variety of physical and mental differences within a society raise issues of distributive justice that have no obvious analogue for other stigmatized groups. A “gender-neutral” environment can be readily conceived, and achieved at modest cost. In contrast, disability scholars and activists have not specified what it would mean to achieve an “ability-neutral” environment—one that was no more advantageous to people with some physical and mental characteristics than others. And some argued that the ideas of an “ability-neutral” environment is either conceptually incoherent or prohibitively expensive (Barclay 2011, 2018). Moreover, it seems likely that questions about the extent to which justice requires reconstructing or modifying the built environment would arise with respect to people with disabilities even in a society with no history of invidious attitudes or practices toward such persons. By contrast, it seems less likely that such questions would arise in a society with no history of sexism, for example.
