Based on the nature of the constitution and the provisions on the powers of the federal government, the American system has created a limited government scenario as the mandate of the federal government are limited by the fundamental constitutional provisions (Ginsberg, Lowi and Weir 47).
Through different approaches, the federal government controls the supply of money into the economy as a way of strengthening the currency and inflation. Through this function, the government ensures that the economy is protected from the impacts of credit and financial crisis as witnessed in the previous years. The federal government is also constitutionally required to regulate the trade within different states in the country and with international markets.
This ensures that unscrupulous trading activities are controlled and illegal entry of products restricted. Treaties that border on security and protection of the territorial boundaries of the country like the north Atlantic treaties are a role of the national government. As a result, no other branch of government or state can declare war against a foreign country as this is the constitutional role of the federal government (Ginsberg, Lowi and Weir 46).
The role of the national government on issues that affect the life of the citizens has remained a controversial issue and this contributed to the limitation of the powers of the federal government. Before the American civil war, debates on the scope of the powers of the national government raged but most believed that the limitation of the federal government power would be in the interest of the people. The debates influenced the limitation of the powers of the federal government and different reasons have been cited for the limited nature of government in the country (Ginsberg, Lowi and Weir 73).
One of the main contributing factors was the legacy of revolution which created the fear of the establishment of centralized power system
