Materialism (adj. materialistic) is the importance a consumer attaches to acquiring and consuming material goods. Also called acquisitiveness, is often associated with a value system which regards social status as being determined by affluence (see conspicuous consumption), as well as the belief that possessions can provide happiness. Environmentalism can be considered a competing orientation to materialism. Materialism can be considered a pragmatic form of enlightened self-interest based on a prudent understanding of the character of capitalist society. However, studies have found that it is also associated with self-destructive behavior and depression.
