The problem of mass production is not that there is too much demand for production but rather too much supply. There is the constant danger of glutted markets. This in turn leads to the need to create demand.
As author Mark C. Taylor notes: “If people buy only what they need, the wheels of production grind to a halt.”
“The necessity of creating mass consumption to absorb the excess produced by mass production led to the invention of a new industry—advertising. One of the most important purposes of advertising is to create desire where there is not necessarily need” (Mark C. Taylor, Speed Limits: Where Time Went and Why We Have So Little Left, Yale University Press, New Haven, 2014, p. 97).
