The antagonisms in the development of modern social relations make working out the idea of creating comfortable life conditions for a person in society topical again. This circumstance suggests reconsidering the theory of a just state within the context of the philosophical conception of the institutional person with a substantial comprehension of the institutional organization of society comparing it with the variability of the tasks of modern democracy. The philosophical concept of the institutional person concerning a just state as a rational concept-construct for a human life and the organization of society continues a series of scientific articles on the concept of the institutional person: the ontological and value foundations which reveal its new possibilities for the analysis of social being. When considering the problem of the formation of a social state as a rational concept-construct for a human life and the organization of society through the prism of the philosophical concept of the institutional person, the principles and mechanisms of its solution are revealed. The paper draws attention to the natural processes of the formation of the middle class and the development of value consciousness which, while maintaining functional differentiation in society, form its social and class homogeneity defining the common tasks of modern democracy aimed at aligning the private interests of the domestic bourgeoisie with the national and regional interests of the country’s development and the personal interests of a human being, and to the painless transformation of domestic oligarchs into aristocrats, into allies of the middle class.
