How exactly is this the case? By all metrics, humans love consumerism and it, or rather capitalism, allow us to enjoy an exceedingly high quality of life.
Manufacturing and agriculture combine to less than a fifth of American GDP today; I say it would be better quality of life if Americans worked one day a week for the same material possessions, but the drive to consume ever more is the primary impediment to that. Similar arguments apply in the other G20 economies, but I’m not going to quantify them.
Of course, I’m not an economist, so perhaps I’m doing a gross disservice to the real value of the service sector…
Convincing them to voluntarily transfer their wealth to someone else is the goal of consumerism, hence the ridiculous money spend on propaganda convincing people they need more things than they want.
The museums around here insist the two big problems were the secret police and the fact that production wasn’t very well matched to demand. Even if you ignore the literal Stasi, I think you may be understating the impact of the shops running out of various foods from time to time.
The point of consumerism is to act as a motivator for the working class to keep working. Once you have that plentiful food and safe & warm hut, assuming that's all there is to aspire to, it would be very tempting to stay home from work on Fridays.
The bigger lesson: Humans don't desire consumerist society.
