Industrialization brought many improvements to America. Perhaps the most important improvement was that all sorts of goods became widely available once industrialization became widespread.
There are two reasons for this. First, industrialization allowed things to be mass produced at relatively low prices. This allowed regular Americans to afford a variety of products that would once have been too expensive for them. Second, the industrial revolution allowed for the creation of a massive transportation network. This network allowed raw materials and finished goods to be transported across long distances relatively quickly and inexpensively. When this happened, businesses could grow bigger because they could sell to more people. This, in turn, allowed them to make and sell products even more cheaply.
