The Math of Human Connection
Heather McGhee’s The Sum of Us is essentially the 'Why We Can't Have Nice Things' guide to America. If you've ever wondered why the U.S. lacks the robust public infrastructure of other wealthy nations—universal healthcare, world-class transit, free higher ed—McGhee points to a specific historical turning point: the moment we decided that if 'everyone' got to use it, nobody should have it.
'The tragedy is that they believe they can't win unless somebody else loses. But this is a lie.'
That quote is the heartbeat of the book. McGhee uses the drained pool metaphor to show how white communities in the 1950s and 60s literally destroyed their own luxury—grand, beautiful public swimming pools—rather than integrate them. It’s a haunting image that sticks with you long after you put the book down.
For a teen reader, this is a crash course in critical thinking. It teaches them to look past the headlines and see the underlying systems. It’s a great companion to a high school civics or history curriculum, but it’s also just a solid read for anyone who wants to feel a little less gaslit by the current state of the world. If your kid liked Stamped or Caste, this is the logical next step that adds the economic layer to the conversation.
The teen-sized edition: The Sum of Us (Adapted for Young Readers) is the official young readers adaptation of this book (ages 10–16) — same core ideas, shorter and gentler in the telling. The right handoff for a curious kid who isn't ready for the original.
