Interesting, perhaps, is the fact that at disability hearings nobody represents the government at all. The claimant often has a lawyer, but the government doesn’t. All the government (usually a contractor) does is get records from the doctors or shrinks the claimant tells them about. Sometimes the government sends the claimant to some doctor for examination, but often not, and that doctor doesn’t get the funds to do any real testing.
And that, as well as the claimant’s testimony, and that of a “vocational expert” is all the evidence that ever gets presented. A lawyer who knows his/her way around the system knows the vocational expert has a very mechanical system to “input” the physical data into, and steers the medical to fit the criteria for “total disability”.
And nobody represents the taxpayers in all of that. None at all.
Very rarely, SS will send out investigators on a “complaint basis” if it sounds plausible. But they’re not well budgeted either, and investigations are very rare.
With a system like that, it’s a wonder everybody isn’t on SSD. Well, if your tax returns show you’re working more than some minimal number of hours/week, then you won’t get it unless you quit right before your case is filed.
