Summarize the message John Galt gives to the people when he takes control of the radio frequency.

He identifies himself and tells the political puppets and the general population that they are reaping what they have sowed. He informs them that the great minds that have dropped out will not return until they can effectively correct all the wrongs that have been done. He informs everyone that he has removed the "victims" of the parasites who have destroyed their work and creativity.
