You don't get rich writing science fiction. If you want to get rich, you start a religion.
L. Ron HubbardDarwin found out that when you took horses up to the high country in the Middle East, they would then grow long hair after a season or two. But when you took them - these long-haired horses - back into the low, hot country, they wouldn't get rid of the long hair, just in case, for about four generations.
