I think what most people here object to is not a natural operation of market forces, which obviously has buying and selling as two of its main components on one side, and on the other production and operation. That dynamic is as unavoidable as human nature, because property is an inescapable human reality.
However, when consumption becomes too elevated in people's lists of concerns, like these people who live for Star Wars or Marvel movies, then you have a problem. There is no scientific measure to this, but a sane man recognizes a consoomer when he sees one. A twitter account named Moldbugman had a recent thread about a guy making a comic book overview of his whole life now at 30, and at every stage he was defined by the brands and entertainment he consumed, or was eagerly waiting to consume in the future.
People now seek fulfillment from entertainment, but also participation, ritual, mythology and religion. They incorporate it into their lives like people used to incorporate all of their culture – the only difference now is that the culture is copyrighted and owned by giant corporations, which even if we discard any malicious intent beyond greed, have a greedy incentive to incentivize such a consumer culture. People depend on culture to survive. Privatizing culture like this, where all of its mythology and ideas are owned by someone, is extremely dangerous and destructive.
These people are trying to fill a God shaped hole in their hearts, with whatever is offered. But not just a God shaped hole, like 100 years ago, but now as a natural progression the hole has widened, now it’s a God, Church, Tribe and Family shaped hole, as all those things withered away. Modern people are close to having nothing BUT the material. It’s not surprising they seek what they lack in the only place it is given: the market. But we shouldn’t pretend this is healthy just because, technically, everyone consents to each individual interaction.
Because of the fact that children are not allowed to work, they spend their earliest and most important years participating in the consumer culture, while having little to no responsibility in production. So they are reared into this mentality. If you add all the ‘make-work’ or ‘high intensity’ type jobs that exist in the metropolitan area that perfectly support this culture in a variety of ways you end up with large chunk of the population whose whole lives revolve around consumption in one form or another. But not just consumption, but one of a specific kind. If I pick some fruit from a tree in the forest and eat it, that is consumption, but it's not the same as me buying a cheese burger at McDonalds. So it's this specific, multinational consumerist culture which is the problem, not consumption.
Another problem is that advertising has ceased to be about presenting products for 60 or 70 years now – it sells you a lifestyle, a cause, an idea. It persuades you not to buy a product, but to elevate yourself to a higher plain of existence… by buying shoes or dishwasher detergent. The goal is not to inform you, but seduce you. On the other hand, it also started to drive everything else: magazines started selling for less than production costs, because they would make up for it in advertising. So reaching more people and advertising more became synonymous. Same thing on tv, and now same thing for the internet.
These are just some of the problems. There are many more. They aren’t caused by the market, but they also cannot be fixed by the market. It has to be an external moral framework that provides the market with a direction.
