The article was exactly what I wanted to say and what I tried to say. I wasn't nearly as analytical or eloquent though. The author is right about one thing; those with the most value to the community will be able to survive, and probably in relative comfort. Question is, what skills would be most valuable? Obviously medical; like he said not all the doctors would starve. What else? Blacksmithing? Farming? Weaving/sewing? Specialized skills like setting up a water distillery? Any other ideas?
What scares me the most is the loss of modern medicine. If that happened I would be among the early ones to die off. Insulin dependent diabetic is not a very livable/survivable prospect in TEOTWAWKI. I would probably end up among the looters looking for vials of insulin and syringes at pharmacies and such. What a way to go.
Of course that would not be the only problem. What about immunizations for babies? Could small pox become a problem? What about tetanus? No more antibiotics? Small infections would suddenly be big problems. Little house on the prairie meets mad max. I for one hope it never happens.
