I'm sure some of them are jobless and would love to be paid $28k a year to do something they already do as a bit of a hobby.
You're also entirely missing my original point. The people currently doing the job don't like it. They don't want to be doing it. And yet they are. Why do you suppose that is? Perhaps... because there are no other jobs available? Saying "you should be looking for a new job" to these people is like telling a homeless man he really ought to be looking for a rental property in his budget range.
It's like having someone with poor sense of smell take out the garbage.
No, it's like having someone a poor sense of smell detect which things smell and which things don't.
Not to mention, having them do this work is taking advantage of a dysfunction rather than helping to address it. In fact it would be likely to make the dysfunction worse.
I'd guess most can identify murder and gore films even if they don't mind them. They're pretty obvious.
I don't understand why taking advantage of this "dysfunction" is a bad thing.
What you see as dysfunction, their apathy when viewing bad content, is their normal state of being.
Why do you think some folk are drawn to habitually view such content?
What other things do you think satisfy that impulse?
Curiosity, memento mori maybe.
It's paradoxically unusual but at the same time incredibly relatable. Everybody dies, so there will be broad spectrum curiosity for the subject, inhibited only by natural squeamishness.
Years ago when highschools still had shop classes, the teacher showed my class a binder full of color photographs of what a lathe accident looks like. The lesson was that lathes aren't toys. I'd never seen anything like those pictures before. They were disgusting, and fascinating. Probably psychologically damaging, but not as damaging as getting caught in a lathe. Did I mention the pictures were fascinating? For most people, seeing that sort of thing is rare. Some people are drawn to novelty, particularly when they can relate to it. Very little in life is as relatable as death; death is even more universally relatable than eating.
Is the suppression of squeamishness a form of mental illness, or a form of psychological damage? I think it definitely can be. But I'm far from convinced it necessarily is.
Because their squeamishness is suppressed to an extent that is unusual among the general public, and what remains is the now uninhibited fascination.
