How does U. S. foreign policy change during the Gilded ages

In United States history, the Gilded Age was an era that occurred during the late 19th century, from the 1870s to about 1900. The Gilded Age was an era of rapid economic growth, especially in the Northern United States and the Western United States. As American wages grew much higher than those in Europe, especially for skilled workers, the period saw an influx of millions of European immigrants. The rapid expansion of industrialization led to a real wage growth of 60%, between 1860 and 1890, and spread across the ever-increasing labor force. The average annual wage per industrial worker (including men, women, and children) rose from $380 in 1880, to $564 in 1890, a gain of 48%. Conversely, the Gilded Age was also an era of abject poverty and inequality, as millions of immigrants—many from impoverished regions—poured into the United States, and the high concentration of wealth became more visible and contentious.

the underground railroad (apocope of the metropolitan railroad) is a system of urban trains located within a city and its metropolitan area. it is characterized for being a massive transport of passengers in the big cities, uniting diverse zones and their environs, with high capacity and frequency and in segregated form to other systems of transport. metropolitan railroads are built underground or on the surface, although most systems use mixed models where sections are combined in both modalities.

1 - as a result, the metro tends to reduce car travel for two reasons: first, due to the greater transfer of users from the car and, second, due to the reduction in the acquisition of cars in homes located in sectors near the stations of the metro.

2 -the metro allows to contribute effectively to the achievement of all the objectives of an urban development policy: it improves the efficiency of the city's economy by reducing travel costs and also generates a higher level of activities in the city center, taking advantage of of the agglomeration economies.

3 -it is a clean means of transport, since it uses renewable energy (usually electricity), taking care of the environment and avoiding excessive pollution.
