The book covers an interesting and growing theory for how intellectual advancement has changed the landscape for how we work. in a nutshell, Schwartz is saying that most workers do better work and feel happier when they believe that they are contributing to something larger than their wallet. When the most mundane of jobs is approached with a sense of purpose and engagement it can be a source of joy… in theory.
My issue with the book is that it seemed to repeat the same chapter over and over. It made the same point regardless of the fact that the same exact story was told in the previous chapter. More of an essay than a book. IMO
