Answer:
The Gilded Age
Explanation:
The Gilded Age is the name that historians have given to the period between 1870-1900. The phrase "Gilded Age" from a satyrical novel by Mark Twain, in which he criticized the bad social conditions, and corruption, that were disguised under a thin veil of gold.
This thin veil comes from the fact that this period was one of great economic expansion and industrialization.
