Economic growth of the U.S from 1865 to present

I already wrote a 5 pages paper about the Great Depression and World War II, please extend this paper to at least 9 pages and describe the economic growth during 1865 to the great depression and after the WW II.
The paper should include the major historical facts which contribute to the U.S economic growth (such as railroads building and growing of steel industry in late 19 century)…
Citation format is not required, you can use resources from any website. Please use subheading to differentiate each period(1865-1929,1945-present)
I’ll upload the 5 pages paper after bidding.
