The Tuttle Twins and the Miraculous Pencil

"Do your kids know how the free market works? Ethan and Emily Tuttle have grown up taking for granted the many things they use: clothes, cars, homes, backpacks--even something as simple as a pencil. In this fun adventure to an amazing factory, the twins learn why even the common pencil is a miracle--one that nobody actually knows how to make--and how the process by which it is made is the key to prosperity in our modern age. Based on the classic essay "I, Pencil" by Leonard Read, your children will learn about the economic principles of spontaneous order, division of labor, competition, trade, and the free market--and why these things bring the people of the world together in peaceful cooperation."--Page 4 of cover.
