alt Hacker NewsSure, but when farmers where 90% of the labor force many of the remaining 10% also related to food distribution and production, a village blacksmith was mostly in support of farming, salt production/transport for food storage, etc.
Food is just a smaller percentage of the economy overall.
Was there ever a time when 90% of labor was in farming and we had anything resembling an economy?
I would have assumed that if 90% of people are farming its largely subsistence and any trade or happened on a much more local scale, potentially without any proper currency involved.
