Answer:
Subsistance farming
Explanation:
Throughout most of history, most of the lower class practiced subsistance farming. This is a type of farming practiced in a small, or medium-sized farm, and that only yields an amount of agricultural output enough for survival.
Any surplus output, if the farmer is lucky enough to achieve so, would generally be given to a landlord, feudal lord, aristocrat, or any other type of military power in exchange for protection.
