Chapters
This chapter explores the complex global supply chains involved in manufacturing a seemingly simple object: a pencil. It uses Leonard Read's essay "I, Pencil" to illustrate the intricate network of individuals and processes that contribute to its creation, highlighting the role of free markets and the invisible hand.
  • The manufacturing of a pencil involves a vast, interconnected global supply chain.
  • No single person understands the entirety of this process.
  • Free markets and the price mechanism facilitate this complex coordination.
