Federalism was introduced in the United States in 1787 and refers to a system of government where power is shared between a central federal government and state or regional governments. The Philippines has debated adopting federalism to decentralize power away from Metro Manila and give more autonomy to local regions to address local issues. Supporters argue this could boost local economies and reduce dependence on the capital, while critics warn it could increase costs and the power of political dynasties. Overall, there are reasonable arguments on both sides of the federalism debate in the Philippines.
