2) "The Unwinding" by George Packer - Packer is my favorite US journalist working today. He argues that societies go through periodic periods of unwinding and that US has experienced one since the 1970s. The books follows six people in-depth but also uses the stories of famous individuals who have influenced the unfolding of this period.
He recently published a magisterial article in the Atlantic worth checking out: https://www.theatlantic.com/magazine/archive/2024/07/phoenix-climate-drought-republican-politics/678494/
