Our world is a material chain of the interconnected systems. For the first time, the author of this book attempts to describe the economic system at the level of an independent state through the language and methodological principles of General System Theory. You will learn what the elements of the economic system are and how they function; about the peculiarities of correlations; how the formal and informal structures are formed; where objectives originate from; and that the planning and forecasting are not alternatives to the market but rather are quite compatible therewith. A huge portion of the book is devoted to the question of money, including where it originates from and what its new theory might be. The book is designed for those who understand the imperfections of the current politics, economy, social life, and who seek solutions to the existing problems. The book is written in simple language and therefore is understandable for both the students and the teachers, and even for those who are not quite familiar with the basics of the Economics. This book is designed for those who are simply not indifferent to the fate of the country in which they live and the lives of people living therein.
