What are some economic struggles the us had during reconstruction

Reconstruction—there were massive changes in American culture, economy, and politics. These were the years of the “Old West,” of cowboys, Indians, and buffalo hunts, of cattle drives, railroads, and ranches. It was also the beginning of the “Gilded Age” in the North, the age of big fortunes, enormous businesses, struggle over labor unions, and the burgeoning of cities filled with immigrants. Hope this helps you out :)
