Explanation:

In 1873, Mark Twain coined the term "Gilded Age" to signify the decades that preceded the Reconstruction era. There was a great shift in the social and economical life in America during the age. The advancement in the technology, economy, and social norms presented a forged image of society. On the one hand, the economy was at its boom, while on the other hand, the discrimination, poverty, and racism saw their progression. The phrase 'Gilded Age' presents the age in real terms. The economic upliftment on the surface hid the poverty and suffering behind its glittering sheet.
