What principles underlie the foundation of American democracy?

The principle will be Equality, Justice, and Liberty.

Explanation:

Democracy throughout the U.S is guided by three values around which the country's economic socio-political structure is founded: liberty, freedom, and fairness (justice).

The nation, therefore, advocates equality for all its people, seeing this right as that of the privilege of every male and female to determine their respective existence without even any restriction whatsoever. To do this, it is the role of the government as well as the legislation treat everyone equally reasonably, that is, there was no other advantage than economic worth.Ultimately, the convergence of both principles means the creation of a just society in which the honest is compensated as well as the incorrect is persecuted and in which the fruit of each dedication and commitment is received.
