I did social security casework after I graduated (helped constituents who got lost in the system on behalf of the member of Congress) and received grateful phone calls from people I'd helped all the time (weekly).
I refer my clients to their congressman all the time to check on the status of their Social Security disability application.
Although I know they're not "lost in the system", it's just going to take them a year to get their hearing.
I suppose "Social Security Disability representative" is always an available job. I think you have to take a test to be able to rep people before the SSA.
