The Impact of Egoistic Behavior on Fiscal Policy Read Post »

This interdisciplinary study analyzes how egoistic behavior adversely affects fiscal policy, linking institutional economics, political theory, and moral philosophy. The research critiques the structural embedding of self-interest within fiscal systems, highlighting examples such as the Trump presidency and tax reforms. It reveals that egoistic behavior leads to regressive taxation and undermines public services, thus eroding democratic trust. The study also contextualizes fiscal dysfunction historically, urging reforms that emphasize ethical accountability and participatory democracy to restore fiscal policy as a tool for justice and equity. Ultimately, it proposes a roadmap to reclaim fiscal governance as a public instrument reflecting collective needs.
