The phrase "pie in the sky" originated from an early 20th-century labor song titled "The Preacher and the Slave" by Joe Hill. In the song, Hill criticizes the idea of the afterlife as a consolation for the oppressed working class, dismissing it as "pie in the sky" that distracts them from their struggles in the present.
