1.Difference between federal, confederation and unitary systems lies in the hierarchy of power distribution. Federalism gives up a large number of powers of individual states to the federal government. It aims to create a strong union that takes on the responsibility of homeland security, unified currency, and the power to challenge states’ laws. States have independence but compare to the confederation system is limited. The Confederation system puts more power into the hand of each state. Powers that I listed before could end up fall into states. The unitary system takes an aggressive approach that aims to create a strong centralized government in return weaken the idea of two-level government.
2.By dividing power into different branches, each branches take some power but also restricted by other branches. It achieves a balance of power. The idea is to use this balance of power to eliminate the chance of having too strong of a government that end up dominating its citizens. In detail, Legislative branch represent citizens, it has the power to make laws and impeach a president. The Judicial branch is the court, it interpret laws and rules them. The head of Executive branch is the president. It is responsible to carry out the law, president is also the head of the military.
3.One outstanding interaction between the federal and state government is grants. According to the U.S. Department of the Treasury website, the federal government is giving out multiple funds to the local government to help relief COVID-19. CORONAVIRUS STATE AND LOCAL FISCAL RECOVERY FUNDS, Capital Projects Fund, Homeowner Assistance Fund, Emergency Rental Assistance Program etc. Adding up to over four hundreds of billions of dollars in assistance.
