We do better on some things (energy production, automobile, ..) but globally the climate changes remind us that consumerism is way too high, and often hype-driven
My point here is that even following a big Kuhnian paradigm shift you're still going to have the same human psychologies to deal with and that's precisely where, "consumerism" lives-- in consumers; the idea that, "consumerism" is somehow driven by ideology or how capitalism structures society seems to be naive in my view. Conspicuous consumption still takes place in supposedly, "destratified" societies-- see the Kim family of North Korea or rich Saudis.
