OK, let's try a specific solution.
Social Security and Vocational Rehab (in each state) should be reoriented toward the organization of worker-owned collectives, owned and run by the disabled.
Since no person, who may be disabled, is absolutely disabled, there will be some talent opposite of the disability. With that,a diverse collective can promote a variety of talents. People, who may be unable to work in the present system, might find that they can produce by sharing that production with others.
Government institutions should be required by law to assist in the organization of these collectives by providing:
1. A means of communication. The disabled can't form a collective unless they know about each other. This would not require violation of confidentiality.
2. Training. That class would be taught be people experienced with collectively run businesses.
3. Funding – in the long run money paid out for disability would reduce, and the people would be producing.
If these government institutions are contracting services to a private corporation, they would be required to shift that contract to a collective owned by the disabled.
