While this is an interesting response, affluence or poverty is obviously a false dilemma. My concern is quite different from your takeaway. As the world is becoming more affluent traditional companies like MCD, MSFT and WMT are more likely to grow their profitability than any company spending money on sustainability efforts that are not required by law or that increase profitability. It's not unlike a prisoners dilemma. We humans will continue to choose what's best for us individually and the outcome will very likely be sub-optimal. I'm not judging, just observing a 60 year climate trend, the ho-hum response and adjusting my investing and family location accordingly.
