A historic example is cited as the French Revolution. I would say first that kakistocracy technically refers to the corrupt and licentious peak immediately before the Revolution; and second that they seem to have forgotten about the fall of the Roman Empire, also preceded by decadence of legendary depravity.
Maybe I should stop saying "panem et circenses" and try to find the original name of that idiotic dish that used lark's tongues in aspic. Which wasn't even any good. I bet you could drop that on the White House table and the Eater in Chief wouldn't even get the reference.
