If the state worker is actually attempting to defend his position, then I would suggest that the best way to try to convince him is in front of an audience.
Years ago G. Gordon Liddy had an FM radio program in the DC area (it was syndicated but never extremely popular). Given his experience, he was always quite vocal about his general disdain for prison guards. Any time the topic came up he would point out that they were not "correctional officers", they were guards. He would explain that there is no correction of anything going on in prisons, and that most of them were nothing more than centers for criminal higher learning.
Well, one day a fan called up who happened to be a "corrections officer", who wanted to take issue with Liddy about this. He got a minute or two in about how it is an important job with very little appreciation, and Liddy immediately challenged him about the title: show me one thing you have corrected. He couldn't, and as soon as he tried to change the subject, Liddy ended the conversation by repeatedly interrupting him with this simple statement:
"Sir, you make your living looking up the anuses of other men."
Now, that guy didn't get converted at all, but a whole lot of his radio audience now hears only that one sentence when they year the words "corrections officer".
Here I am about 13 years later, reading books about alternative legal systems, all because I was made to wonder once about whether we really need to be paying men to look up the anuses of other men.
