A good possible vocation for people with disabilities is in schools as teacher's aides,libraries, sports aides, street crossing guards etc.People with disabilities can have slower movements which fits in  well with underage children who also have slower movements. Having a capable teacher's aide helping children with an art project while the teacher is freed up to work intensively with other students can be very helpful in a classroom. Also a classroom is usually a more helpful, loving, accepting, non judgemental environment which is a better fit for people with disabilities. The point about education is to get everyone studying, working, moving. All jobs are important and should be professionalised. If someone is a carpenter he should know the building codes and the proper application of materials. There's so much to learn  to be a good carpenter like architecture, structural support, design, footings, wiring, plumbing, concrete etc. Courses should be strategic and students should have a good understanding in all aspects of building so people don't get ripped off by fake  "contractors" who are clueless. There should be a practical application to study. People who are studying to be nurses can be used in hospitals for patient care like feeding, changing linens, bathing patients. These practical hands-on opportunities are so important in helping the next generation of nurses and carpenters. If these positions are well paid, not too stressful and well organized people will want to do them.
