The purpose of this paper is to understand why unemployment improvement and social inequality occur at the same time. For this question, a key factor is the capitalisation of work-related social security, such as environmental, social, and governance (ESG) resulting from digital transformation (DX). This paper will discuss two crucial points of the capitalisation of social security. In the real sense, investment performance is not a fundamental solution to problems. As such, it will be essential for trade unions, who function as pension managers, to address these problems as a countervailing power.
