I wonder if doctors get elevated on these polls because people feel like it is a more unattainable skill.

I would imagine a lot of people (falsely) assume that it would be easy to plop people into power plants to keep them running, but harder to replace doctors.

My completely unknowledgeable take is that if we had to pick and choose people for the post apocalypse job hunt, we would want way more mechanics and engineers than doctors. Doctors need a lot of hard to obtain stuff to do the most doctor-ey part of their jobs, and if we aren't worried about laws and regulations, then we don't need them for things like prescriptions.

Most of what they would be needed for in that scenario to me seems like emergency care, like first aid, which you don't really need all the superfluous med school training for.

Meanwhile, the hydroelectric dam that the new post apocalypse group is forming at needs a lot of varied disciplines and specialties just to keep it running.
