 As these examples suggest, the fact that disability-related disadvantages often reflect contingent features of the social environment may have different relevance for different decisions and decision makers. Parents deliberating about whether to have a child with a severe disability may need to treat as “given” the adverse effects on well-being of social stigma or inadequate educational resources. It is far less clear that legislators would be justified in treating as “given” the reduction in well-being associated with these social conditions, given that they are in a position to modify those conditions, by, for example, prioritizing funding for inclusive education.
