The Right Not to Work: Power and Disability

"While issues regarding racial, gender, and sexual orientation equality are all at the forefront of political and social theory, disabled people are almost always left out of these conversations. The disabled are viewed with sympathy as victims of “bad luck” who will simply have to accept disadvantage as their lot in life, not as an identity group that is systematically discriminated against. Unlike sexism and racism, which are perceived to be significant social problems, disability falls under the social radar and disablism is not recognized as a damaging or even particularly serious form of prejudice."
