It's been drilled into the head of every public school kid for decades. I get surprised looks by people when I tell them we do not live in a democracy, you have been brainwashed.
"The deliberations of the Constitutional Convention of 1787 were held in strict secrecy. Consequently, anxious citizens gathered outside Independence Hall when the proceedings ended in order to learn what had been produced behind closed doors. The answer was provided immediately. A Mrs. Powel of Philadelphia asked Benjamin Franklin, “Well, Doctor, what have we got, a republic or a monarchy?” With no hesitation whatsoever, Franklin responded, “A republic, if you can keep it.” (Benjamin Franklin) "
Another worth mentioning,
“I think with you, that nothing is of more importance for the public weal, than to form and train up youth in wisdom and virtue. Wise and good men are in my opinion, the strength of the state; more so than riches or arms.” (Benjamin Franklin, Letter to Samuel Johnson, August 23, 1750.)"
