What role does laissez-faire immigration urbanization and the rise of the middle class have on the gilded age?

During the Gilded Age, laissez-faire Immigration policies facilitated a massive influx of immigrants seeking economic opportunities, which fueled rapid urbanization as cities expanded to accommodate the growing population. This urban growth contributed to the rise of a distinct middle class, as new job opportunities in industries and services emerged. The combination of these factors led to significant social and economic transformations, with stark contrasts between wealth and poverty, ultimately shaping the landscape of American society during this period.
