Since the advent of civilization, humans have had an impulse to form governments. It is an experiment thousands of years in the making. This website asks a lot of fundamental questions about the nature of government and society. Among them:
What is the purpose of government?
What types of governments are there? What is a democracy?
Where is the center of governmental power? Is it national or local?
Is America's government too big? Too small? Constantly shifting with the times?
What are the rights and responsibilities of each American citizen?
We do not answer these questions; that is up to you. Defining the role of government has been thousands of years in the making. Welcome to the laboratory of democracy.
