Well an obvious answer would be slavery, depending on how late you're talking. After slavery ended, the country began what is known as the "industrial revolution". The north had already begun industrializing for a while, but in the 1870's and beyond, things ramped up quite a bit. Factories for clothes, shoes, farming equipment, packaged foods, and etc. became more popular. You also had coal mines, railroads, and steel mills. This showed the country was moving in the direction of mass production, and moving away from agricultural ways of living. This also meant child labor, which led to many child labor laws in the later years. This also meant many moved out of farming communities, and into larger, noisy, and crowded cities. Many immigrated to the US to take advantage of that, which led to some tension between communities.

US Containment Policy is a foreign policy strategy created and executed by the US after WWII founding it’s first key purpose in the Truman Doctrine of 1947. President Harry Truman warned of the evils of communism<span> that threatened the democratic freedom of its people which like the US, the Soviet Union wanted a world modeled on their own country’s society and values. Even though the Soviet claimed they provided all citizens with economic and social rights, the US saw communism as a slave state that control the private life and thoughts of its citizens. A threat that violated both democratic rights and civil liberties of its citizens and therefore required the continued efforts of America to make sure that it did not spread to the United States and other nations that have not yet moved politically towards Soviet Union communism. As such, this Policy of Containment stated that the US would try to stop (contain) the spread of Communism by creating strategic alliances or support to help weak countries to resist Soviet advances.
