Mass consumption
A society of mass consumption is contrary to a society of mass poverty. In a society of mass poverty, the average level of consumption is low, and most of the people consume a small amount of goods. (see graphs in the exhibition). In a society of mass consumption, the average level of consumption is very high and most of the people  consume a large amount of goods.
The society of mass consumption is the result of a higher purchasing power, as well as of social struggles for a better share of the production benefits. Mass consumption makes possible bigger markets (super and hyper), but it is not an egalitarian society.
