What was the overall impact the Second Industrial Revolution had on America?

The Second Industrial Revolution impacted the United States in many ways. When the Second Industrial Revolution began, more people began to work in factories. The working conditions in these factories were very poor. Workers were often injured on the job. They worked long hours for low pay. Children often worked in the factories. Eventually, laws were passed to deal with these conditions.
American industrial production increased. New and cheaper methods for making steel were used. This allowed for significant advances in transportation. Steam engines were used to power ships and trains. More miles of train tracks increased the areas to which railroads could travel. Products and people could be transported faster. New roads and canals also improved the transportation system. American products could now also be shipped around the world, opening new markets to American businesses.
Communications also improved. With the invention of the telegraph and later the telephone, it became easier and quicker to communicate. This allowed businesses to receive and process orders more quickly, allowing for these businesses to expand their operations.
The Second Industrial Revolution allowed the American economy to grow and to prosper. While there were some issues connected with the Second Industrial Revolution, the United States benefitted from it in many ways.
