How was american society different in 1933 than in 1789?
Answer:
There are many differences between the society of 1789, just a few years after the United States was formed as a new independent nation from its motherland, England, and the America of the Great Depression and pre-Second World War.
To start with in 1789, America was still just finding the balance to work as a real independent nation. George Washington, the hero of the Revolution, was assuming power, but there were still a lot of political differences and debate, over how exacty the nation would be run, and how power would be divided. In 1933, though debates were still present, the two-party system was already established, the roles of each institution of the American government was cemented and now it faced two huge problems: the Great Depression, and the initiation of conflict in Europe, just after the terror of the 1st World War.
In the America of the 1789, there were still some who identified themselves with the British, and who desired a return, or a reconciliation at least, with their motherland. Yet in 1933, the balance had been turned. Americans had their identity as such fully formed, and it was Britain now who began to depend on the help and aid of the U.S.
But probably the greatest difference was exactly the Great Depression of 1929, and which devastated America, its institutions and its society, and the two World Wars, the one that had just ended, and the one that was beginning to brew. These events together helped to further cement the identity of the American, enforce it and re-inforce it. Socially, there was a lot of struggle, as the country fought both the bout of the Depression and the Golden Eras to find a balance. Whereas in 1789, the issue was still the differences between states, those of the North and those of the South, the ones who supported slavery, and the ones who did not, and the issue of the Indian Nations, and how to handle them.
These are in summary, some of the things that made the American society of the 1930´s different from that of the 1780´s.
