Hyperconsumerism

Hyperconsumerism, hyper-consumerism, hyperconsumption or hyper-consumption refer to the consumption of goods for non-functional purposes and the associated significant pressure to consume those goods exerted by the modern, capitalist society, as those goods shape one's identity. Frenchy Lunning defines it curtly as "a consumerism for the sake of consuming."
