You’re wrong, it falls under some minority belief. Even the president of France said last year “we’re living the end of abundance” and he’s a liberal productivist. Abundance is clearly at most a target of healthy minority within a non heathy society.
I don't know if this was intentional on your part, but that Macron quote appears to be grossly out of context: he said it in the context of an expected difficult winter due to the war in Ukraine and an ongoing drought in Europe[1]. He ties it more broadly into consumer changes that will need to happen as part of climate change, but he's not talking about an end to the kind of baseline abundance that citizens of modern developed countries expect (around competing products in their stores, etc.).
(And in case it isn't clear: I'm entirely for reducing society's unnecessary forms of consumption, especially when it comes to personal modes of transit, wasteful packaging, and unsustainable residential patterns. But abundance is an independent variable.)
