What were the improvements that industrialization brought to America?

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.
