The Gilded Age.

The Gilded Age: A Tale of Today is an 1873 novel by Mark Twain and Charles Dudley Warner that satirizes greed and political corruption in post-Civil War America. Although not one of Twain's better-known works, it has appeared in more than one hundred editions since its original publication. Twain and Warner originally had planned to issue the novel with illustrations by Thomas Nast. The book is remarkable for two reasons–-

it is the only novel Twain wrote with a collaborator, and its title very quickly became synonymous with graft, materialism, and corruption in public life.

The term gilded age, commonly given to the era, comes from the title of this book. Twain and Warner got the name from Shakespeare's King John (1595):

"To gild refined gold, to paint the lily... is wasteful and ridiculous excess."

Gilding a lily, which is already beautiful and not in need of further adornment, is excessive and wasteful, characteristics of the age Twain and Warner wrote about in their novel. Another interpretation of the title, of course, is the contrast between an ideal "Golden Age," and a less worthy "Gilded Age," as gilding is only a thin layer of gold over baser metal, so the title now takes on a pejorative meaning as to the novel's time, events and people.
The theme of the novel is that the lust for getting rich through land speculation pervades society, illustrated by the Hawkinses as well as Ruth's well-educated father, who nevertheless cannot resist becoming enmeshed in self-evidently dubious money-making schemes. The main action of the story takes place in Washington, D.C., and satirizes the greed and corruption of the governing class. The book does not touch upon other themes now associated with the "Gilded Age”, such as industrialization, monopolies, and the corruption of urban political machines. This may be because this book was written at the very beginning of the period.
The novel concerns the efforts of a poor rural Tennessee family to grow affluent by selling the 75,000 acres (300 km2) of unimproved land acquired by their patriarch, Silas “Si” Hawkins, in a timely manner. After several adventures in Tennessee, the family fails to sell the land and Si Hawkins dies. The rest of the Hawkins story line focuses on their beautiful adopted daughter, Laura. In the early 1870s, she travels to Washington, D.C. to become a lobbyist. With a Senator's help, she enters Society and attempts to persuade Congressmen to require the federal government to purchase the land. n the end, Laura fails to convince Congress to purchase the Hawkins land. She kills her married lover but is found not guilty of the crime, with the help of a sympathetic jury and a clever lawyer. However, after a failed attempt to pursue a career on the lecture circuit, her spirit is broken, and she dies regretting her fall from innocence.
Washington Hawkins, the eldest son who has drifted through life on his father’s early promise that he would be “one of the richest men in the world,” finally gives up the family's ownership of the still-unimproved land parcel when he cannot afford to pay its $180 of taxes. He also appears ready to overcome his passivity: "The spell is broken, the life-long curse is ended!" Philip, drawing upon his engineering skills, discovers coal on another characters land, wins that characters daughters heart and appears destined to enjoy a prosperous and conventionally happy marriage.
