I don't see how your reply connects with what the parent said. But to your point, I don't think anyone in this conversation specifically claimed anything about workers of the third world needing to be prevented from taking these jobs, but rather how they're universally harmful to the human mind.

This could imply banning the industry, but since most agree it's necessary, most would probably be in favor of psychological counciling and greater pay for these workers.

The point is we're subjecting desperate people to trauma before limited to first responders, police, and military, while providing them none of the pay, job security, or counciling of these above specialities.
