Explain why the produce from tropical plantations are profitable to the local comunities that can grow them, but not as profitable as finished goods

The profit margin for local growers usually from a minimum of 45% to as much as 1500%. Like any farmer, these percentage of profit are variable and are controlled by several factors like weather, pest, and others. Unlike finished goods, product cost is maintained up to 30% only of the selling price ensuring profit for every sold item. Also, finished goods are priced higher than that of raw a material like local produce.
