Pat Franks, who wrote "Alas, Babylon", used his personal experiences in WW1 and WW2 to come up with the list of shortage items for his book. Salt, coffee, alcohol, medical supplies, gasoline, car batteries, tires, clothes, and shoes are just some of the items he mentions.
Alot of people don’t think about salt.
Salt is cheaper than dirt right now.
But in the past, alot of people worked their backsides off and sweated and toiled and then got paid. They got paid in SALt. Which was SALine.
That’s where we even get the word SALary.
A guy could put 100 lbs of SALt up for like what, maybe 20 bucks?
