I support the medical model then, disabled people who can't work should, ought, to be among the poorest in society, just above the people that can work but don't. Because some people have to be the relatively poor compared to the rest (in absolute terms though: you are richer than almost anyone alive in year 800 CE so not starving poor nor barely surviving poor) and so, who should be? Should the able working be poorer than a disabled person doing less work? The same work?
And why should disabled people be able to craft policy that will be funded largely by the abled? In order to have legitimacy of a policy, you need to involve the people that will pay for it.
The social model is non-sensical, it's unfair, and it cloaks its unfairness in the language of social justice which it doesn't deserve to. There are better forms of advocacy.
