They took this word out of the dictionaries over a hundred years ago. https://en.wikipedia.org/wiki/Kakistocracy
kakistocracy (n.) "government by the worst element of a society," 1829, coined (by Thomas Love Peacock) on analogy of its opposite, aristocracy, from Greek kakistos "worst," superlative of kakos "bad" (which perhaps is related to PIE root *kakka- "to defecate") + -cracy. Perhaps the closest word in ancient Greek was kakonomia "a bad system of laws and government," hence kakonomos "with bad laws, ill-governed."
