Even more insulting is that these men's visages ended up on fiat currency issued by a central bank.

George Washington, $1 bill, 25¢ coin:

"Paper money has had the effect in your state that it will ever have, to ruin commerce, oppress the honest, and open the door to every species of fraud and injustice."

Thomas Jefferson, $2 bill, 5¢ coin:

"The central bank is an institution of the most deadly hostility existing against the Principles and form of our Constitution. I am an Enemy to all banks discounting bills or notes for anything but Coin. If the American People allow private banks to control the issuance of their currency, first by inflation and then by deflation, the banks and corporations that will grow up around them will deprive the People of all their Property until their Children will wake up homeless on the continent their Fathers conquered. The issuing power should be taken from the banks and restored to the people, to whom it properly belongs."

and

"Banking establishments are more dangerous than standing armies."

and

"The bold effort the present (central) bank had made to control the government … are but premonitions of the fate that await the American people should they be deluded into a perpetuation of this institution or the establishment of another like it. I am one of those who do not believe that a national debt is a national blessing, but rather a curse to a republic; inasmuch as it is calculated to raise around the administration a moneyed aristocracy dangerous to the liberties of the country."

Abraham Lincoln, $5 bill, 1¢ coin:

"The money powers prey upon the nation in times of peace and conspire against it in times of adversity. It is more despotic than a monarchy, more insolent than autocracy, and more selfish than bureaucracy. It denounces as public enemies all who question its methods or throw light upon its crimes. I have two great enemies, the Southern Army in front of me and the bankers in the rear. Of the two, the one at my rear is my greatest foe."

Andrew Jackson, $20 bill:

"Gentlemen, I have had men watching you for a long time and I am convinced that you have used the funds of the bank to speculate in the breadstuffs of the country. When you won, you divided the profits amongst you, and when you lost, you charged it to the bank. You tell me that if I take the deposits from the bank and annul its charter, I shall ruin ten thousand families. That may be true, gentlemen, but that is your sin! Should I let you go on, you will ruin fifty thousand families, and that would be my sin! You are a den of vipers and thieves. I intend to rout you out, and by the Eternal God, I will rout you out... If people only understood the rank injustice of the money and banking system, there would be a revolution by morning."

Benjamin Franklin, $100 bill:

"The refusal of King George to allow the colonies to operate an honest money system, which freed the ordinary man from clutches of the money manipulators was probably the prime cause of the revolution"

Ulysses S. Grant, $50 bill:

"The government should create, issue, and circulate all the currency and credit needed to satisfy the spending power of the government and the buying power of consumers. The privilege of creating and issuing money is not only the supreme prerogative of government, but it is the government’s greatest creative opportunity. The financing of all public enterprise, and the conduct of the treasury will become matters of practical administration. Money will cease to be master and will then become servant of humanity."

Franklin Delano Roosevelt, 10¢ coin:

"The real truth of the matter is that a financial element in the large centers has owned the government since the days of Andrew Jackson."

John Fitzgerald Kennedy, 50¢ coin:

"For we are opposed around the world by a monolithic and ruthless conspiracy that relies on covert means for expanding its sphere of influence--on infiltration instead of invasion, on subversion instead of elections, on intimidation instead of free choice, on guerrillas by night instead of armies by day. It is a system which has conscripted vast human and material resources into the building of a tightly knit, highly efficient machine that combines military, diplomatic, intelligence, economic, scientific and political operations."

You want irony? This is the hydrogen bomb of irony. We believe these men upheld the values that our money system represents, therefore most people simply do. not. question.

To put these men's faces on our currency is flat out the absolute most outrageous posthumous insult they could possibly endure.
