Consumerism is the idea that increasing consumption of goods and services purchased in the market is always a desirable goal and that a person's wellbeing and happiness depends fundamentally on obtaining consumer goods and material possessions. In an economic sense, it is related to the predominantly Keynesian idea that consumer spending is the key driver of the economy and that encouraging consumers to spend is a major policy goal. From this point of view, consumerism is a positive phenomenon that fuels economic growth.
