Have you ever wondered why we can afford so many more clothes than our grandfathers, but not a house in which to store them? Why can the price of gasoline double in a few months, but falls much more slowly? Why do the governments of certain countries ignore some terrible conflicts taking place on the planet, but do not hesitate to intervene in others? Economics is behind all this. Darshini David invites us to follow the journey of one dollar around the globe. Today, the US economy is less than a quarter of the world's, but 87% of transactions concluded in foreign currencies are made in American currency – dollars. Having analyzed how money exchange occurs - physical or digital - the author tries to unravel the tangle of financial transactions that determine our lives in all its manifestations. Each of the chapters in this book is an important piece of the puzzle, clearly demonstrating exactly how our world functions, who really has power and how it affects us.Darshini David is a writer, economist and television presenter.
