If Chaucer had just had subsistence farmer after subsistence farmer telling their tales it would be very boring. Even in such a society, there were a number of different roles at the bottom of it. Some people were shepherds or drovers rather than just scraping the soil, others were producing cloth and clothing, others were fishermen, others were midwives and so on. All these were useful at the time and used by peasants.
