In the course of evolution, humans have developed an "underlying protocol" that balances self-interest and fairness, characterized by tension and flexibility. Like "an ancient scale within the human heart," this protocol adapts to complex social interactions. The rapid collapse of the Soviet-style socialist bloc, the social prosperity of contemporary "full-fledged democratic" blocs, and comparisons between China’s patrimonial bureaucratic dynasties and the 15 historically enduring states (each lasting over 500 years) all indicate a direct causal relationship between this underlying protocol and the fate of nations—with power being an exceptionally unique variable.
