The Industrial Revolution created two classes within the cities: the owners and the workers. The working class lived in tenement housing. They often had to buy things that they would have made or grown themselves when they were farmers, making them even poorer.
Technology contributed to the creation of US cities because it had a lot to do with the “urban design” of those cities. For example, when technology allowed taller buildings to be built, cities were able to have denser populations. They were also able to have huge skyscrapers in which thousands of people could work, thus strengthening cities as a center for jobs. At the same time, technologies such as street cars and then private automobiles changed the urban landscape. Instead of having people of all classes living together, there came to be more segregation on the basis of class. People who had more money were able to use the new technology to commute into cities to work. This allowed them to live farther out from city cores, either in city limits or in the suburbs.
