The article examines the experience of the USSR in the field of solving the problem of correlation between social justice and economic efficiency. The characteristics of those aspects of Soviet experience in the sphere of implementation of social justice principles in the sphere of labor and distribution, which have potential for application in the conditions of modern capitalism to respond to the current challenges, are outlined. Firstly, it is noted that social justice is not reduced to inequality of income and distribution of wealth but is considered in connection with the human factor of economic development. In an expanded understanding, social justice includes a measure of access to basic resources such as labour, housing, education, health and other areas of human development. The experience of the USSR is characterised by the fact that, on the one hand, the universal availability and security of these basic resources (public goods) created the grounds for stimulating human development. On the other hand, the violation of these declared principles in practice (due to the development of bureaucratic privileges and benefits, the shadow economy, etc.) caused serious negative incentives, which became one of the elements in the system of reasons for the departure of “real socialism” from the historical scene. Secondly, the article points out that the Soviet system of income generation based on the principles of labour distribution was a combination of planned-normative and market-capitalist principles designed to create economic “egoistic” incentives. To the extent that this system was implemented, it succeeded in stimulating productivity and labour (but not market) initiative. But the manifestation, and in later stages of the USSR's development – in some cases the predominance, of bureaucratic-voluntarist foundations in the system created rather negative incentives. Relations of alienation in the sphere of appropriation and disposal of public property undermined socialist incentives to work and social innovation. The author concludes that some of the achievements of the Soviet system in the realisation of social justice are possible and effective in meeting the challenge of sustainable development in the 21st century. In particular, practices that were developed in the Soviet system, such as the provision of basic goods that are publicly available and free to users, the use of forms of work organisation based on a combination of competition, solidarity and self-government, etc., remain important.
