Which part of the u. s. economy had the biggest boost after world war i?

The U.S. won World War I and set up the League of Nations to decide on what to do with Germany and Italy. The Treaty of Versailles was also signed that set limits on the future of Germany. America did not sign due to unrest at home. Actually- The League of Nations was a condition contained within the treaty of Versailles. Because of a lack of support in Congress, the United States never signed this document and therefore never entered this collaboration between nations. Due to the United States' lack of participation, the League of Nations was not long lived, and not until the creation of the United Nation (WWII) did the United States become involved in an international coalition such as this.

The case was a u.s. supreme court decision that defined the scope of the u.s. congress's legislative power and how it relates to the powers of american state legislatures. the dispute in mcculloch involved the legality of the national bank and a tax that the state of maryland imposed on it.
