Real nurse has to deal with real blood and real gore. If you believe those mods should be paid more, you are out of your mind.
Anyway, this type of jobs will be soon replaced by AI classifiers. Nobody will suffer anymore.
Also, on AI classifiers, I think there are far too many nuanced situations to completely replace mods, and your comment about this is very hand-wavy, and even if you are right, we still need to deal with the problems we have now, not defer them by saying there will be a solution in the future.
But I am sure many of them would take this work for a bit of extra money. There are people from Middle East, Ukraine, Romania... We had millions refugees passing through Athens just a few years ago. Reality is simply very different here.
