After so many years of riots and political scandals, America reached an era in which business was doing great " the gross national product climbed from $70 billion to $100 billion - and people were having a lot of fun. After the riots people wanted to "return to normalcy'- and so the Republican Party came went into office since a long time. The Republican Party helped America prosper with it's probusiness stance. This "allowed old industries to grow rapidly and new ones to enter the ranks of the corporate giants-.
The majority of the people were happy with how things were going; "an avalanche of new products transformed their lives "none more so than the automobile-. The Ford revolutionized the car industry forever, it started the assembly line, which allowed factories to churn out goods faster, and with prices so low that even the workers could buy them. The government spent billions of dollars to encourage Americans to travel around. With so much freedom of movement, America, for the first time, had more people living in the urban areas than in the rural and with the car they could visit their families that stayed in the farms. .
Electricity also revolutionized America. By the end of the 1920s over two thirds of all homes in America had electricity; electricity usage almost tripled. The invention of the light bulb contributed a lot to this. Another milestone of this era was the invention of the radio. Since some people were better paid they had more free time in which they turned to the radio. By the end of the decade the radio reached around 10 million homes; the radio became a common household appliance. .
The radio contributed to new trend: Jazz. Jazz originated among African Americans in the south, and as it became popular on a national lever, jazz adapted in various ways. Jazz gave black people more confidence and it gave a rise to the black artists to a movement known as the Harlem Renaissance.
