In a true post apocalyptic world, a real collapse of civilization, you must first think of the basic human needs. Food, shelter, security. Secondly
would probably be medical knowledge and energy production.
I Agree that a jack of all trades would be more valuable, however some seemingly single skills require a subset of many skills.
Food: Someone who can farm and produce large quantities of crops or livestock will be valuable. Farming a large piece of land and have it produce a
usable crop is different from growing your own small garden. Also, trapping and hunting would be valuable. Each of these require knowledge that is
best learned through experience, not from books.
Shelter: Anyone can build a basic shelter. You don't need to be an engineer to build a shack that can protect you from the elements so I don't see
this as an essential skill. Plus, engineering skills could be learned from books. Techniques, formulas, principles etc, could all be learned by an
intelligent person from books. I think builders and carpenters would become more valuable later on as things settle down and people want to have
larger and nicer structures built.
Security: While having weapons and the skills to use them properly will be valuable, it's not the only thing you should worry about. I don't see a
shortage of armed people happening. But, being able to organize those people into a formidable force instead of a bunch of individual wannabe
commandos will be a valuable skill. Survival types will probably be ok but the average group of mindless people will need a leader.
Medical knowledge: I see hands on skills being more important than general knowledge. Knowing how to treat wounds, administer first aid, perform
surgery, etc.. Sure, I can stitch up a small wound, but what happens when your appendix bursts or someone shoots you for your can of spam? You gonna
trust your neighbor to cut you open or would you rather have a surgeon do it? Secondly would be someone with the safe manufacture and administration
of medications, both synthetic and natural.
Energy: I would imagine someone who can produce bio diesel and build a wind turbine would be pretty high on the friend list. Knowing how to make and
repair batteries would probably be a good thing to know. Do you know how to produce sulfuric acid and repair a car battery? They're good for more
than cars. It might be good to know.
