Thanks very much for sharing this - definitely a topic I would to explore further.
But yes, it raises good questions - how do we frame the idea of not spending on things we don't need in a way that is acceptable (and even positive - I believe this is possible, to find ways to make connection and belonging, which do more for our well-being, more important than "stuff") to people with a diversity of worldviews/experiences/ideologies?
(And also with sensitivity to genuine needs - I'm not sure anyone needs a private jet or a yacht, and much commercial air travel could be avoided, but asking people to entirely sacrifice traveling for medical care or to be with family could make them not want to sacrifice anything...)
