** C M Kornbluth's "The Marching Morons" (novelette, satire)

A variation on "selling ice to Eskimos" theme. A no-morals man from our time ends up in a future where average IQ is 45, & there is an exclusive breed of smarter people confined to Antarctica. In a deal that promises to make him the ultimate dictator, this man helps the smart ones kill off rest of humanity by selling them a story that makes them want to march off to their death.
