I can't even begin to follow the logic for this.
There are probably plenty of people on disability who could, in theory, work if they could find a job that both matched their existing skill set and accommodate their particular needs, but those are big ifs. Obviously if your job is to sit in a nice office chair writing missives to the world you can contemplate working with all kinds of medical conditions. A plumber with back problems? Not so much.
That perhaps some older marginally disabled workers who were laid off in this recession might be getting some disability benefits is a good thing, unless making them homeless and penniless is your preferred outcome.
