Answer:
Mark Twain
Step-by-step explanation:
The term "Gilded Age," coined by Mark Twain and Charles Dudley Warner in their 1873 book, The Gilded Age: A Tale of Today, was an ironic comment on the difference between a true golden age and their present time, a period of booming prosperity in the United States that created a class of the super-rich. 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."
