The public health systems of liberal states systematically fail to meet the goals and obligations of the Convention on the Rights of Persons with Disabilities, which aims to facilitate full societal participation and independent life choices by all impaired persons, as well as the unburdening of their private caretakers. This failure does not stem from a lack of money or effort by governments and other societal institutions, but flaws in the anatomy of these systems. As these systems confine institutional assistance to the needs of persons with certain delineated disabilities, they neglect the needs of other persons, whose disabilities do not fit this mould. The responsibility for the latter group thus falls to their immediate social circle. These private caretakers are in turn seldom supported. To remedy this situation, I will present the alternative paradigm of vulnerability theory as the possible foundation for a more inclusive approach to public health.
