For instance, the majority of people are forced to sell their ability to work for a wage. And scarcity is an artificial situation caused by capitalism’s rule of no profit- no production.

Scarcity is a situation where there is not enough to satisfy everyone's wants.

scarcity is the condition of being scarce or less.

Usually associated with a certain quantity. Like scarcity of water in a desert. Scarcity of rain in a region

Scarcity is the fundamental basis of economics. Without scarcity, there would be no economy.
