I don’t think you are insensitive at all.
BUT, even if the urbanites know these skills, where would they practice them? It’s too crowded in the city. So they head out for rural areas. That is already owned by other people? From what I have read, a great deal of the rural residents survived the Great Depession far better than the city dwellers. (maybe not the dust bowlers)
I consider myself, and all on this thread, pretty blessed if we are rural, with property and know how to make the best use of the situation.
Rule 1 of survival: if in a bad place, MOVE.
Rule 2: if you can’t, do something sensible and proactive.
Yes rural survival is easier - start walking and get out of the concrete jungle already!
