It's a bit self-feedback for sure. Corporations have an interest in producing as much as they can, as rapidly as they can, because that means they have more goods to sell, which means they can afford to sell them cheaper (funny joke I know) and thus, bring in a larger market. If no one is buying anything, sure, corporations will stop their mega production, but until it hits a certain level, they're just gonna keep going. If we could convince like, 75% of people to adopt a waste conscious attitude towards consumerism, we'd probably see production drop significantly, but I'd say before that it's going to be a less than linear result.
It's probably easier to convince enough of our representatives to do something for their constituents benefit for a change. Or work on getting a representative elected that actually gives a shit. People don't like to compromise when it impacts their way of life too dramatically, unless everyone has to make the same concessions.
I have zero formal education in this topic btw. Any numbers were pulled straight out of my ass, so please don't quote me lol
