Notice how the other side keeps making my case for me. Rich people overdosing, depression at any income level, luxury buying only temporary satisfaction. That's not proof money buys happiness, that's evidence it doesn't. Money might buy security, and I'll grant that. But past sufficiency, extra income mostly becomes more stuff, more flights, more emissions, and the climate stability and healthy communities that actually sustain wellbeing get eroded. So money can rent comfort for a while, but it can't buy the stable ecological conditions happiness really depends on.
