This made the traditional belief which was built on the foundation of modesty and fairness lose its sense. Therefore, human dignity was deconstructed and the desire for civilization and democracy was replaced by material pursuit. Power and wealth had bee the center of life. However, we know Mark Twain always had a dream for a highly civilized society. The reality was far away from what he dreamed for. So he was quite disappointed at the society. Moreover, the USA entered the period of imperialism. The country invaded other countries in the whole world in order to open a market for its products. Twain witnessed the colonial war while he was in roundtheworld lecture tour. He had a deep aversion to the evil behavior. The Man that Corrupted Hadleyburg, written in 1900, was set in such a social background. In this work, the nieen principle citizens deceived each other and disguised when they were faced with a bag of gold. This was a true portrayal of the capitalist society, or we can say, the nieen principle citizens were a symbol of imperialism. Twain mercilessly criticized the social corruption and hypocrisy in American as well as the magic and evil role money played in the society. However, Mark Twain took the greed and selfish nature of the capitalist as all the citizens’ in mon, which made the work shroud in pessimistic color. And pessimistic idea continued in his old age. Twain’s pessimism, which is shown in The Man that Corrupted Hadleyburg is also related to his personal experience in the 1890s. In 1894, his investments of the typesetting machine and the publishing pany failed, which brought a debt of one hundred thousand to Mark Twain. Therefore he had to make a roundtheworld lecture tour to earn money for the debt as a sickly man of nearly 60 years old. Later，he ever used words to describe his feeling to the bankruptcy, which was “ pain despair and be torn with grief”（ Twain, 76） . The bankruptcy was a huge hit to Mark Twain in material, while the death of his beloved daughter brought great pain to his spirit. Just during his tour, on the 15th of August 1896, when Twain was standing in a dinning room, thinking of nothing in particular, a cable was put into his hand, “ Susy was peacefully released today.”（ Twain, 110） Twain, unprepared, could hardly accept the thunder stroke like that.
