The Industrial Revolution changed the way of life that people have been so used to for generations and readied future generations for even more advanced machines. Many inventors such as Eli Whitney and Samuel Slater made many different machines such as interchangeable parts and the Pawtucket mill. However, the Industrial Revolution did not only make more advanced machines, but it also changed many things to do with workers and jobs. For example, in workhouses before the Industrial Revolution, many employees worked “10 to 14 hours a day, six days a week, with no paid vacation or holidays,” (Effects of the Industrial Revolution). From everything the workers had to do with all the heat in the factories, there were many accidents that happened. Trade unions stood up and spoke up about the issue. Eventually, President Martin Van Buren made a workday cut down to only 10 hours maximum. This let workers regain their strength before they had to go back to work the next day. This also made the workers do better at their job. Another example, is how the population grew during the Industrial Revolution. Many workers, unskilled or skilled, migrated towards the Northeast to get a job. So many workers came to get jobs that “small towns became large cities,” (Effects of the Industrial Revolution). Many of these workers made families while they were here, which means that the population for America was growing. Since the population was growing, the United States was expanding and making the country more like a country. The Industrial Revolution was not only a part of the American history, but it changed the unfolding of American history.
