THE PURPOSE OF GOVERNMENT Magruder’s American Government; pp 8 – 10 What does government do? A meaningful answer to that question can be found in the Constitution of the United States. The American system of government was created to serve the purposes set out there. “We the People of the United States, in Order to form a more perfect Union, establish Justice, insure domestic Tranquility, provide for the common defense, promote the general Welfare, and secure the Blessings of Liberty to ourselves and our Posterity, do ordain and establish this Constitution of the United States of America.” ~ Preamble to the U.S. Constitution
