I'm reading William K. Klingaman's book "The Darkest Year: The American Home Front 1941-1942" and I'm up to the parts where rationing is going on: sugar,
coffee, meat, tires, gas. I found this part interesting from a
permie perspective:
The cut off line was "from converting garages into stables."
Looking at the world around me right now, I can see a strong possibility that building wagons or raising horses NOW might be a good investment of time and
energy for a permie who is inclined to do either of these things. The time period in the book was very early on in car culture, there were still wagons around that could be found and cleaned up. There were still horses easy to find to pull them. Neither of those is true right now. And if things get bad
enough that having that technology would be profitable, it will be late for ramping up production. Horses or mules take time to grow up,
wood and any needed metal for wagons is easier to deal with if you have a truck to get it and power tools to make them. If wagons are needed, the resources to make them easily will be very limited. "No one was making new wagons in the fall of 1942, due to shortages of metal and wood."
It's a thought worth considering.
