Question : Why did salt used to be so expensive?
I was reading Wikipedia…

“However, salt was difficult to obtain, and so it was a highly valued trade item. Until the 1900s, salt was one of the prime movers of national economies and wars. Salt was taxed from as far back as the 20th century BC in China.”

Why was salt so hard to find? Isn’t the ocean full of salt? Isn’t that where sea salt comes from? I just don’t get why it was so valuable if the world is full of it.
national movers
