The book explains basic economic concepts, ranging from the most famous theories, such as Adam Smith's "invisible hand" and the law of supply and demand, to the latest ideas about the connection between wealth and happiness, and the forms and principles of economics in the 21st century. The book sheds light on important topics: why there is a boom in the economy, why it is replaced by a recession, where the roots of crises grow, who the “bears” and “bulls” are, how economics is connected to politics, whether the social sphere is a shackle on the legs of the economy or quite the opposite how to get rich and how not to get poor. This is a real encyclopedia, simple, accessible and completely accurate in terms of ideas and facts. An ideal tool to combat economic illiteracy.
