Two decades into the twenty-first century, the stagnation of living standards has become the defining trend of American life. Life expectancy has declined, economic inequality has soared, and, after some progress, the Black-white wage gap is once again as large as it was in the 1950s. How did this happen in the world’s most powerful country? And what happened to the “American dream” – the promise of a happier, healthier, more prosperous future – which was once such an inextricable part of our national identity?

Drawing on decades of writing about the economy for The New York Times, Pulitzer Prize-winning writer David Leonhardt examines the past century of American history, from the Great Depression to today’s Great Stagnation, in search of an answer.
