Need help answering a couple questions about the Banking Crisis/Civil War. Please help me.10 points for answer?

From the end of the Civil War to 1900 industrialization radically changed the United States. How did the industrialists like Cornelius Vanderbilt and Gustavus Swift help create that change, for good or for ill, and how did these changes affect the workers' lives?. How did the workers' fight back and how did the farmers fight back with the Populist party.??
