After World War one ended in Europe, nations across the globe could finally focus on getting their countries in check, both politically and economically. The United States was a great example of this. The time period after the war in the U.S was known as the roaring twenties. This was because the economy simply boomed for the Americans. The stock market was hot, everyone had a job, people were spending money, and women were given suffrage (the right to vote). From an economic standpoint, Americans were making a lot of money through manufacturing of automobiles, and the entertainment industry. The Ford model T car came about in the twenties. Ford was selling these cars for $440, they made 15 million of these cars by 1927, and they produced the assembly line which allowed them to produce the output of the cars they were making. Jazz came into effect in the 20's along with the start of the movie industry. A lot of attraction came out of those industries and thus, money was pumped into the economy of the United States. Politically, America was focused on Isolationism as there political philosophy. This meant that they stayed out of international affairs such as the League of Nations for example. They were focused on their economy, no one else's. The Americans were doing so well that this just seemed like the logical thing to do. The United States of America was possibly in the best condition it had ever been in in the 1920's.
