Scarcity refers to a state of being in short supply.
Scarcity exists because distribution of resources is unequal. Majority of the people tend to get more than they need in preparation for future uses. They did not take into consideration that other people also need the items they have stocked up on. This results to unequal distribution of resources. Those who had first access to the goods have more than they need while those who came last have goods that is not enough to sustain their needs. They are the ones experiencing scarcity.
