Theoretical Disputes and Distributive Justice: Historical Observations on the US Progressive Income Tax System

The progressive income tax system is a major model innovation in personal tax changes. Based on the historical observation of the US personal income tax system, it is conducive to the dialectical analysis of the rule of law value, theoretical connotation, and comparative advantages of the progressive income tax system. The benefit theory explains the effectiveness of the progressive income tax system in distributing benefits; the sacrifice theory integrates the welfare of the individual and the state in the progressive income tax; the faculty theory emphasizes the concern for the individual's “ability”; and the justice theory clarifies the systemic significance of the progressive income tax system from the perspective of the rule of law for the development of society. These four theories provide a systematic evaluation of the progressive income tax system from different perspectives, which can help people better understand the reasons for the emergence of this tax system. On this basis, the comparative observation of the system advantages of the progressive tax can also highlight the rationale of a progressive income tax system in terms of social governance.
