From H.L. Mencken (1880–1956), American journalist, essayist, satirist, cultural critic and scholar of American English. Notes on Democracy (1926):
Democracy is a pathetic belief in the collective wisdom of individual ignorance. No one in this world, so far as I know—and I have researched the records for years, and employed agents to help me—has ever lost money by underestimating the intelligence of the great masses of the plain people. Nor has anyone ever lost public office thereby.
