The book is not about mechanical engineering, as one might think from the title. A book about the processes taking place in society. About its mechanisms. And about you and me, about ordinary people, who are the lubricant and fuel of these mechanisms, who are victims of the life of society as a whole or its individual layers. After all, it is the ordinary person who is the main victim of the cataclysms occurring in society. All persons who are higher in the social hierarchy have a greater chance of not suffering from the tragedy occurring in society. And often they are beneficiaries. And only a simple person is always a victim.
