The main finding of the critical analyses of the past (ex-Yugoslavia) and present (Venezuela, Argentina...) economic self-management and political self-government attempts to overcome class division of labor between rulers and ruled at all levels of social life reproduction, identifies the main obstacle to realization of social justice and democracy in twofold activity of global financial oligarchy to perpetuate capitalist mode of production. The first activity concerns manipulation of formal participation of wage workers in corporations and citizens in parliamentary elections as an organizational technology for reduction of its management costs and domestication of the governed. The second activity concerns privatization and imperialist control of natural and social conditions of social life reproduction of the rest of humanity through violent recolonization process. The way for overcoming this obstacle to realization of social justice and democracy is found in self-managing and self-governing theoretical and practical activity of the rest of humanity based on drawing lessons from and avoidance of deficiencies of previous historical attempts to overcome class division of labor and capitalist mode of production.
