Beyond that, a lesson in listening to and respecting scientific warnings about climate change and other existential threats we'd rather not think about. Lessons about not blindly listening to economic advisers who want numbers to go up and, hopefully, lessons about how humans can revert to human kindness and decency when faced with real issues. I think of the stories from NYC about so many people helping each other on 9/11 - we need to become real communities again to work through this together.
