Money can't buy the things that actually sustain happiness, and past a point it buys ecological damage instead. The other side is right that cash gives access to water and food, but money doesn't create soil or clean water, it just allocates them, and overconsumption degrades them. The data is pretty clear: wellbeing gains flatten once basics are covered, and richer countries haven't gotten happier as GDP climbed. So money can buy comfort and stress relief, sure, but not the stable climate and healthy ecosystems that real wellbeing depends on.
