What gives more power to a central government than to local governments?

A central government typically holds more power than local governments due to its authority over national policies, defense, and international relations. It often has the ability to regulate commerce, impose taxes, and enforce laws that apply uniformly across the entire nation. Additionally, constitutional frameworks usually designate specific powers to the central government, reinforcing its dominance in critical areas such as currency and Immigration. This concentration of authority enables the central government to maintain a cohesive national agenda and respond to issues that transcend local jurisdictions.
