A national model for fostering peace of mind through a selective tax system / 選択税制による安心醸成国家モデル

Short Abstract This paper proposes a new national design framework aimed at systematically reducing social anxiety through the structural redesign of taxation and basic living infrastructure. Rather than treating taxation solely as a fiscal mechanism, the study redefines it as a form of psychological infrastructure that shapes human behavior, decision-making, and perceived security. The model integrates a three-tier selective progressive consumption tax with the elimination of fixed basic living costs—such as electricity, gas, and water fees for households—to remove foundational sources of anxiety. The paper introduces the concept of a “psychological multiplier effect,” whereby reduced anxiety leads to increased consumption, naturally strengthening tax revenue without increasing individual burden. Through this mechanism, the model demonstrates the possibility of simultaneously improving fiscal sustainability, well-being, birth rates, public safety, and societal creativity. By framing social anxiety as a layered structure and proposing a phased strategy for its reduction, the study presents a coherent blueprint for a psychologically stable and self-upgrading state suitable for the 21st century.
