Fiat Money

To me, 'fiat money' is simply paper currency printed, enjoys legal tender status but not backed, pegged or decreed by gold.

Here are other more qualified quotes:

"Lenin was certainly right. By a continuing process of inflation, governments can confiscate, secretly and unobserved, an important part of the wealth of their citizens. There is no subtler, no surer means of overturning the existing basis of society than to debauch the currency. The process engages all the hidden forces of economic law on the side of destruction, and does it in a manner which not one man in a million is able to diagnose."
- John Maynard Keynes, `The Economic Consequences of The Peace'

“Fiat money is the cause of inflation, and the amount which people lose in purchasing power is exactly the amount which was taken from them and transferred to their governments by this process.”
- G. Edward Griffin, “The Creature from Jekyll Island”

“A fiat monetary system allows power and influence to fall into the hands of those who control the creation of new money, and to those who get to use the money or credit early in its circulation. The insidious and eventual cost falls on unidentified victims who are usually oblivious to the cause of their plight. This system of legalized plunder (though not constitutional) allows one group to benefit at the expense of another. An actual transfer of wealth goes from the poor and the middle class to those in privileged financial positions.”
- Congressman Ron Paul, "Paper Money and Tyranny"

"It is well enough that people of the nation do not understand our banking and monetary system, for if they did, I believe there would be a revolution before tomorrow morning."
- Henry Ford

"I believe that banking institutions are more dangerous to our liberties than standing armies. Already they have raised up a monied aristocracy that has set the government at defiance. The issuing power should be taken from the banks and restored to the people to whom it properly belongs."
- Thomas Jefferson
