Disability benefit with close to 100% approval rate

I always wonder "For able-bodied poor people with low skill and no intention to take minimum wage jobs, how do they survive after unemployment benefits run out?" Now, I have answer, at least partially, after watching tonight CBS "60 Minutes": "Get the disability benefit". That government benefit almost has a 100% approval rate even you just have, e.g., headache or muscle pain. The number of enrollees in disability program shot up after 2008 financial tsunami. Disability entitlement program is expected to run out of money three years from now and since no legislators want to be labelled as "cold-blood politicians", be prepared to embrace for the next round of payroll tax increase.
