In the medieval times, AKA the feudal system trade was very high because it was needed to get goods the kingdoms were more like places you were forced to live and without trade, you would never get food or clothes. You made less than a penny a day this could pay for a loaf of bread at the end of the week you got one pair of shoes a year and 2 pairs of clothes. When the trade went up it eventually ratified the need for all the work in the kingdoms.
