Among advocates of disability rights, who tend to subscribe to the social model instead, the medical model of disability is often cited as the basis of an unintended social of disabled people. Resources are seen as excessively misdirected towards an almost-exclusively medical focus when those same resources could potentially be used towards things like universal design and societal inclusionary practices. This includes the monetary and societal costs and benefits of various interventions, be the medical, surgical, social or occupational, from prosthetics, drug-based and other "cures", and medical tests such as genetic screening or preimplantation genetic diagnosis. According to disability rights advocates, the medical model of disability is used to justify large investment in these procedures, technologies and research, when adaptation of the disabled person's environment could potentially be more beneficial to the society at large, as well as financially cheaper and physically more attainable.
