From "The Discourse of Voluntary Servitude" (circa 1552) by French political philosopher Étienne de La Boétie:

In short, when the point is reached, through big favors or little ones, that large profits or small are obtained under a tyrant, there are found almost as many people to whom tyranny seems advantageous as those to whom liberty would seem desirable. Doctors declare that if, when some part of the body has gangrene a disturbance arises in another spot, it immediately flows to the troubled part. Even so, whenever a ruler makes himself a dictator, all the wicked dregs of the nation — I do not mean the pack of petty thieves and earless ruffians who, in a republic, are unimportant in evil or good — but all those who are corrupted by burning ambition or extraordinary avarice, these gather round him and support him in order to have a share in the booty and to constitute themselves petty chiefs under the big tyrant.
