I have a good friend who's quadriplegic and they trained him to be a computer design operator (not easy when you only have limited use of your hands!) and got him special tools, etc. and get him a job, but when the economy is bad, he's one of the first laid off since he's slower than most and, businesses have to make money, that's their point, so he goes on and off unemployment (which is different from Social Security or SSI) and then SSDI when that runs out.
