Well, that depends on what you call "able bodied". Let me give you an example. I know a guy who's 36. In the prime of his life. He's got Bi-Polar disorder. It's a real thing, and he has real symptoms. If he goes unmedicated, about twice a year he'll go all "Charlie Sheen" on us and get a little crazy, sometimes even suicidal.
So he needs meds. When he's on meds he's a completely normal dude who goes years without a bi-polar episode. He found himself out of work and applied for SSDI. After all, when he's off his meds he truly is disabled and can't live a normal life. Being on meds though, makes him a completely normal guy who is able bodied and more than able to hold down a job.
So SSDI approved him as disabled, so he could get his meds for free from the government - which he needs. So now he's on meds and completely normal. But if he gets a job, he loses his disability qualification and loses his meds. So instead, he gets a SSDI check every month, gets a govenrment provided phone, got free furniture from a non-profit, gets public housing, gets SNAP, and gets state cash assistance. He basically lives the life of a college kid playing xbox and drinking beer all day in his apartment on the taxpayers dime. He's in a catch 22, if he works he may or may not find a job that covers his expensive medication. If he doesn't have meds he's a crazy threat to himself. But if he stays "disabled" he gets free meds and free everything. It's not a life of luxury, but it's a lot like living the college life in perpetuity. And he's going to get this free ride the rest of his life. He retired from the workforce at age 32! Perfectly able bodied when on his meds, but the system isn't setup for this situation, so us taxpayers get to support him. It's pretty messed up.
