Based on my early studies, I think people's lives changed as a result of the Industrial Revolution in that society completely changed the way goods were produced or manufactured.
Indeed, the Industrial Revolution changed the way of many people. Farmers who lived in the rural parts of the country decided to move to the larger cities such as New York or Chicago, where the big factories were located. Immigrants from Europe and Asia decided to move to the United States to work in the factories. There, people were hired to operate the machines in the mass production system.
