The subject of the study is the creative, socio-cultural potential of labor, capable of going far beyond the limitations of a market economy, reducing labor to the production of material wealth (goods) and profit. The philosophical and cultural methodology is considered, which makes it possible to include socio-cultural, pedagogical, journalistic professional activities, as well as nepotism and large families in productive work. A prominent representative of this approach is the Russian philosopher E.V. Ilyenkov, who, exploring the methodology of K. Marx's Capital, deduced and successfully applied the principles of dialectical logic to solve the most complex socio-cultural and pedagogical problems, including the full-fledged development of deafblind children. The philosophical and cultural heritage of E.V. Ilyenkov was created not in a vacuum, but in the context of a corresponding trend in Russian philosophy (studies by D.I. Rosenberg, M.M. Rosenthal, A.A. Zinoviev, etc.), correlating with the formulation of the basic economic law of socialism in the work of I.V. Stalin "Economic Problems of Socialism in the USSR". The methodological basis of the research is the principles of dialectical logic developed by E.V. Ilyenkov: analysis of the development and results of the confrontation between market and non-market (post-capitalist) trends in socio-cultural processes and their philosophical understanding. The materials are the works of E.V. Ilyenkov, as well as the works of modern researchers, who sometimes evaluate his works from opposite positions. The scientific novelty of the article lies in the polemic with the interpretations of the theoretical legacy of E.V. Ilyenkov as "philosophical dissidence" in the USSR. On the contrary, the connections of the methodology developed and applied by E.V. Ilyenkov with the formulation of the basic law of socialism by I.V. Stalin and the then "social order" for the study of dialectical logic based on the analysis of K. Marx's "Capital" are established. The developments of E.V. Ilyenkov turned out to be unclaimed for a while; the identified reason is the market neocolonial transformation of the USSR. Socio-cultural development was increasingly hindered through the mass formation of harmonious, comprehensively developed, creative personalities and an increase in the wealth of friendly social relations. Recommendations are formulated on the possible use of the philosophical heritage of E.V. Ilyenkov in modern conditions for methodological support of strengthening the state socio-cultural policy, including in the field of improving support for nepotism and large families, solving the demographic problem.
