Rockefeller, J. P. Morgan, and Henry Ford the Gilded Age is a time of big money. Technology boomed with the invention of trains, telephones, electric lights, harvesters, vacuum cleaners, and more. But for millions of immigrant workers, it is a time of big struggles, with adults and children alike working 12 to 14 hours a day under extreme, dangerous conditions. The disparity between the rich and the poor was dismaying, which prompted some people to action.
