Why was the time of industrialization called the gilded age and how did the effects of urbanization contribute to it?

The period of industrialization known as the Gilded Age, roughly spanning from the 1870s to the early 1900s, was marked by rapid economic growth, significant wealth accumulation, and stark social inequalities, which often masked the underlying issues of poverty and corruption. The term "gilded" suggests a thin layer of gold covering a less attractive reality, highlighting the disparity between the rich and poor. Urbanization contributed to this era by concentrating labor forces in cities, facilitating industrial growth and attracting immigrants seeking work, which in turn increased the wealth of industrialists while often leading to poor living and working conditions for the urban poor. This dynamic created a booming economy alongside stark social challenges, encapsulating the contradictions of the Gilded Age.
