Reflecting on my business made me recall something: Many of our forefathers and many poorer people today didn't just have one job or even two jobs working shifts. Most had an occupation at which they worked and their household did whatever it could to get more money or cut costs. For example, if you wanted some extra cash maybe your wife would flowers to sell in town to restaurants for their tables...
While this does not take advantage of the division of labor as effectively as if you completely specialized in a single occupation and paid for everything else with cash, it did create multiple streams of income for the household. In cases where you grew things to sell, you would sell the S and A-tier produce, and use the B-and below for yourself.
