Who is Diana Moon Glampers, United States Handic from Welcome to the Monkey House and what is their importance?

a Moon Glampers is in charge of all handicapping in this 2081, society. It is mentioned briefly that she bears a physical resemblance to Hazel Bergeron. Diana's job is to make sure everyone in the world is equal, with no one having a mental or physical advantage over anyone else. She sets all of the loud sounds that blast into mental handicap radios and controls the timing. Her agents, the H-G men, enforce the laws by arresting and fining anyone who strays from the handicap rules. It is the H-G men who take Harrison Bergeron away to jail, and it is Diana Moon Glampers who enters the television station at the end of the story and kills Harrison and his Empress Ballerina with a double-barreled, ten-gauge shotgun. She then forces the musicians to put their handicaps back on, thus restoring order.
