A buddy of mine was injured by an IED in Afghanistan, he lost his right eye. Every year he goes to the VA for his regular checkup and the doctor has to sign some paperwork that he then needs to get notarized. Social Security says they need all that to make sure he's still disabled... you know, checking that he hasn't spontaneously regrown an eyeball miraculously and would then be cheating the system I guess. Our benefit system for disabled people is really fucking broken.
The cost of this and thousands of other pointless assessments by qualified medical professionals probably costs more than people receive in benefits in the first place let alone the cost of a handful of cases of actual fraud.
If he forgets his appointment or can't otherwise make it, it can take weeks if not months for a VA doc to see him and, in the meantime, he could lose his benies for like 6 months.
