The United States of America is called "The Grand Experiment" because it is the first country to exist that was formed "by the people, for the people" and is based on democracy and liberty.
The USA gave the power to the people as the rulers of the government, instead of as is traditional, where a government rules the people. One of the reasons for the first and second amendments; the freedom of speech and to bear arms.
It was warned by the founding fathers that this state would always be under attack and subject to "change" if it were not for the vigilance of the people. When the people rely on big government they flirt with the loss of this grand experiment.

No free government, or the blessings of liberty, can be preserved to any people but by a firm adherence to justice, moderation, temperance, frugality, and virtue; and by a frequent recurrence to FUNDAMENTAL PRINCIPLES."
- Patrick Henry
