The Convention of States during the Second Great Depression changed the United States of America in several fundamental ways. They repealed the Sixteenth Amendment that allowed the Federal government to directly tax individuals. They repealed the Seventeenth Amendment. That returned selection of Senators to their State governments, giving the States direct control over the Senate again. They also changed how Representatives were selected by implementing State-wide proportional elections for the preferred political party. That ended the Republican-Democrat Two-Party system that had dominated America for two centuries by allowing any political party to win a House Seat as long as they were able to win enough votes in a State that had multiple seats. They added term limits to Federal positions, including the House and Senate. They recalled the new Supreme Court Justices packed into the expanded Supreme Court by the administration of the time. They passed numerous other amendments aimed strictly at curtailing the powers the Federal government had over the States, and placed far harder limitations on what roles the Federal government was allowed to perform. The States went in with the intention of hobbling the Federal government so it could not control them in the future. They succeeded.
