Historically, having to buy a new thing was often not a cause for pleasure, but horror. Because, for instance, a new piece of clothing was woundingly expensive. It had a marked financial impact on a household's budget.
We celebrated as things got cheaper, because it allowed us to buy more stuff and suffer no real financial consequences. But that had a lot of knock on effects. We stopped fixing stuff, and we threw away more stuff, and the intrinsic value of the stuff plummeted. 3/ #eco
