Structural Debug Blueprint for Solving the Declining Birthrate Problem — Reconstructing the Entry Point of Human Reproduction through Disposable Income Maximization —

This paper proposes a structural debugging blueprint for solving the declining birthrate problem by focusing on the “entry point” of human reproduction—marriage and childbirth motivation—rather than conventional policies that only address the “exit,” such as childcare and education subsidies. The study argues that the expansion of precarious employment, especially dispatch labor, has created a reproductive deadlock by eliminating long-term economic expectations for many young individuals. To resolve this structural failure, the paper introduces three systemic interventions: direct tax circulation for dispatch workers to maximize disposable income, tax incentives that transform professional certifications into economic assets, and an educational system shift toward purposeful skill acquisition. By restoring financial stability and future expectations among young adults, the framework aims to remove economic barriers to marriage and family formation and reconstruct the foundational conditions necessary for sustainable population renewal.
