What is the main conflict in Vonnegut's "Harrison Bergeron," and how is it resolved? How does the story's ending make it successful?

The conflict in Kurt Vonnegut's short story Harrison Bergeron is the use of restrictive handicapping devices on the intelligent, talented, strong, or otherwise gifted, in order to ensure total equality in society. For example, the titular character, Harrison, is so talented and strong that he must wear several devices to limit his natural gifts. He is weighed down by heavy hindrances, deafened by large earphones blaring static, and near-blinded by a pair of glasses. Harrison illustrates the conflict between government-mandated limitations and the people burdened with them, because he resists his handicaps on live television. He removes his handicaps and those of a dancer, declaring himself the Emperor and her his Empress, and the two dance around the room.

The story ends with a government official, the Handicapper General, shooting Harrison and his "Empress" on live television. Harrison's parents are watching at home, and the final dialogue in the story adds poignant emphasis to the extent of the limitations placed upon people. Harrison's mother is naturally unintelligent, and his father has been limited by deafening earphones to the point of matching her level of ignorance. The two forget that they have watched their son die on television immediately after witnessing it.
