There are lots of slang words for wages today that have to do with food: "cheddar", "cabbage", "dough", "bread" "bacon" -- maybe future etymologists will assume that we were paid in bread and cheese.
Maybe there's a good reason for the bacon thing, or maybe some guy just tended to buy bacon on payday. /shrug
"It sounds cool and kids' parents hate it" goes back to at least the 50s. It's an arms race of kids/teens trying to invent their own slang that their parents won't understand and then that language being picked up in popular culture and becoming more widely used and then kids try to come up with new terms.
(We had a lot of fun with "yeet," "hype," "been knew," and a few others with my kids a few years ago.)
Most on-line sources claim the phrase originated in 1104 in a small town in Essex, England.
In the third paragraph the author states he prefers the boxer story.
Personally, I think the usage of that idiom is older than 117 years.
Because of the dampness, there's no turf to speak of
and now we have nothing to burn.
This sounds a bit less serious to modern American ears than it should. We think of winter as being annoying, not dangerous.
In China, where a common word for wages is 薪资 -- "fuel and resources" -- people are more likely to intuit that going without fuel is best not attempted, even though they've never experienced it either. It makes for an odd example of poetry coming across better in translation than it does in the original language.
No refrigeration. No freezing. No canning.
They used a lot of salt.
They also had cellars and natural refrigerators.
As it would imply price to be very high. Which then would mean that regular people would not have access. But they also widely used salt. So it could not have been extremely valuable as we understand. Or maybe gasoline is extremely valuable commodity now...
Salt production and trade have been restricted, usually state-owned monopoly. Cities with salt mines like Salzburg became extremely rich, like oil countries today.
Is gasoline valuable? Yes. Is affordable? Yes, but not for everyone. Same with salt back than.
That isn't possible; someone who can't afford salt dies. It's like claiming that water "isn't affordable for everyone". It is, and it must be, because people who can't afford it also can't exist.
Comparisons are very hard, but to put that in a bit of perspective: at an average salary of $60k/yr, a typical American today makes $165/day. So the cost in time for a Roman to buy salt would be roughly equivalent to if the price for salt today were $11/lb.
That's more expensive than it is today (I just bought salt for ~$2.50/lb), but it's a far cry from extremely valuable.
An Army private starts at, $1,833/mo that’s 21k/year. Even corporal is only getting $2,393/mo to start and cap at $2,906/mo w/ 10 years. https://www.military-ranks.org/army-pay
So a modern soldier starts at ~24lb/day of your 2.50$/lb salt, but also has much cheaper alternatives.
You’re right about the wages, but single soldiers live on base (no housing costs) and are also fed (no food costs).
That’s $1,833 per month is all discretionary which is why you hear the stories of 18 year old privates buying a new <insert fast car>. A $800/month car payment is no problem with plenty left over.
And once you get married you can live off base and a Basic Housing Allowance. If stationed in San Francisco (unlikely, but a good example), you get $3,177/month as an E-2 (Private 2nd class).
You get even more money with kids.
Then add on top a full pension after 20 years and full healthcare coverage through the VA.
Overall military pay is actually quite high.
And you need to carry the salt. That's it. Salt can't rot and it's needed everywhere; this is just about the easiest piece of commerce you can do.
And salt was not only flavoring, but one of the few means of preserving food. Access to salt was not a mere culinary issue, it was a matter of survival. This means that there was substantial trade, and substantial value in salt production and trade.
Agree Northern Europe would be tough, but there are plentiful salt ponds in Vietnam where the humidity (plus the rain) would make one think evaporation would be challenging, but apparently it works.
What really made it special was that it was commodity with possibly limited production locations, that kept extremely well and was in steady demand. So it is one thing that everyone uses and is relatively easy to tax. And the price likely was much more stable compared to food and other goods.
The large scale demand also lead to it being desirable as military target, once you control the production you are good.
The reality was just that making salt is an unpleasant, labor intensive task. In the Roman era, this involved slaves and thus capital.
Salt was one of the most important goods that were traded over long distances. And no, technologically it wasn't advantageous to transport seawater or try to convert seawater into salt. Ukrainian city of Soledar that was prominently featured in the news last year literally means "gifting salt" -- and it has huge historical salt mines under it.
So, not only in antiquity, all the way through to the 19th century salt was one of the key goods traded over long distances. It wasn't as scarce as diamonds, but due to high demand it was still a worthwhile thing to trade.
Of course, that's a fringe theory. The most mainstream one is that the copper coins people used for pennies would develop a patina of verdigris and would look, like the Statue of Liberty, green.
