People living with disabilities and other marginalized groups have little voice and social power globally. On the other hand, protection imperatives mean that society implements unique solutions and tries to save them from their fate. Social workers and researchers have both professional ideals and an ethical responsibility for working with and for people with disabilities and other marginalized groups. To succeed, theoretical models are crucial, especially in uncertain times like those we live in today. In social work research, the questions are central for people with disabilities and other marginalized groups. They look different, they need to be investigated differently, and above all, they must be answered in new ways. The growing perception and ideal of inclusion highlight equality and the political right of all people to have the same opportunities for development and a good life in society, regardless of differences in social or financial capital. Inclusion has also been highlighted as a matter of course for people with disabilities. We know that people with disabilities are not a homogeneous group but include people with different types of disabilities and with different functional problems. We also know that people with disabilities in different parts of the world live under different living conditions, have drastically different needs, and have access to very different resources. However, the common denominator is that people with disabilities have less existing social power, defined as access to economic, social, and political resources, and often no gender, ethnicity, or social status.
