The fundamental problem that both producers and consumers face is scarcity.
The scarcity is the lack of basic resources such as water, food, energy, housing, etc., which are considered fundamental to satisfy survival or non-basic resources that meet different needs in human societies in several aspects.
Usually a society does not have enough resources to adequately provide for the needs of its population, so it is necessary to exchange and trade in goods and services. The scarcity obliges to prioritize the needs or goals of the society.
