I want to know the answer to the following question:
Where did the wealth of the Glided Age come form?
All the background I'm provided with is that "During the Gilded Age, there was substantial growth in population in the United States and extravagant displays of wealth and excess of America's upper-class during the post-Civil War and post-Reconstruction era, in the late 19th century.". Is that enough to answer the question?
Answer: no
