Rational Self Interest T-Shirt

The Rational Self Interest shirt is inspired by the philosophical idea that individuals act to serve their own interests — a concept central to debates around ethics, economics, and human behavior.

This graphic tee turns that principle into something more visible.

This graphic tee is perfect for:

• Philosophy lovers and critical thinkers
• Fans of ethics, economics, and human behavior debates
• People who enjoy dark, intellectual humor
• Those drawn to idea-driven, minimal designs
• Anyone who prefers subtle but provocative statements
