the.com/consumerism

means The belief system that treats shopping and acquiring goods as a central, even primary, measure of personal satisfaction and social progress.

from Built from 'consume,' which traces back to Latin 'consumere' — 'con-' (entirely) plus 'sumere' (to take up or use) — originally meaning to use up, devour, or destroy. For centuries 'consumption' was mostly grim, a wasting disease or the using-up of resources. The '-ism' suffix, which turns a practice into a doctrine, got bolted on in the 20th century as economies shifted toward mass production and mass marketing, and critics needed a word for the ideology that consuming itself had become a way of life, even a substitute for meaning.
