After World War II, the German government implemented strict price controls to stabilize the economy during the Wirtschaftswunder. The emphasis on fair pricing was institutionalized as a mechanism to prevent profiteering and ensure equitable access to essential goods. These post-war regulations reinforced the idea that prices should be stable, predictable, and based on objective calculations rather than speculative market fluctuations. The German social market economy emphasizes balancing free market principles with social welfare, including fair pricing practices that prevent consumer exploitation.
