Do you know why people have always lived in poverty in potentially rich Russia? What is the main contradiction of human society? What is social justice and does it exist? Is private property good or evil? Is it possible to combine the economic efficiency of the social system with social justice? Is a non-exploitative society real? Why did Soviet socialism fail and what are the further possible ways of Russia's development? Is it possible to mathematically describe such abstract concepts as ideology, freedom, mentality, social system, and finally, the very inner essence of man?
