 The situation of persons with disabilities is a special ethical concern for health care allocation because disability is not just any human difference—like age, gender or ethnicity—or any social disadvantage—like poverty, gender discrimination, or minority marginalization. Disability is both a difference and a disadvantage that is conceptually linked to a person’s health state, and therefore health needs. All disability theorists these days agree that the physical, social and attitudinal environment in which a person with a health problem or functional impairment lives will make a huge difference to their perceived “disability” the person will experience (WHO 2001). Although there are a few hold-outs of the so-called “social model” that insist that disability is a pure “social construction” that has nothing to do with the state of a person’s health (see Oliver 1990), the Consensus is that disability is conceptually linked to health: without an underlying health problem or impairment there is no disability.
