Well socially it changed with the mass immigration from Europe. The Industrial Revolution happened. The 20's had an economic boom, while the 30's featured a dramatic stock market crash. Socially things changed in the 30's because of the amount of working and non-working people below the poverty line. You can write about the New Deal and WWII both revitalizing the economy.
As far as the Gilded Age I have this: The Progressive Era was a period of social activism and political reform in the United States that flourished from the 1890s to the 1920s. One main goal of the Progressive movement was purification of government, as Progressives tried to eliminate corruption by exposing and undercutting political machines and bosses. Many (but not all) Progressives supported prohibition in order to destroy the political power of local bosses based in saloons. At the same time, women's suffrage was promoted to bring a "purer" female vote into the arena. A second theme was achieving efficiency in every sector by identifying old ways that needed modernizing, and emphasizing scientific, medical and engineering solutions.
Many people led efforts to reform local government, public education, medicine, finance, insurance, industry, railroads, churches, and many other areas. Progressives transformed, professionalized and made "scientific" the social sciences, especially history, economics, and political science. In academic fields the day of the amateur author gave way to the research professor who published in the new scholarly journals and presses. The national political leaders included Theodore Roosevelt, Robert M. La Follette, Sr., Charles Evans Hughes and Herbert Hoover on the Republican side, and William Jennings Bryan, Woodrow Wilson and Al Smith on the Democratic side.
Initially the movement operated chiefly at local levels; later it expanded to state and national levels. Progressives drew support from the middle class, and supporters included many lawyers, teachers, physicians, ministers and business people. The Progressives strongly supported scientific methods as applied to economics, government, industry, finance, medicine, schooling, theology, education, and even the family. They closely followed advances underway at the time in Western Europe and adopted numerous policies, such as the banking laws which became the Federal Reserve System in 1913. Reformers felt that old-fashioned ways meant waste and inefficiency, and eagerly sought out the "one best system". They enacted Prohibition and exposed government corruption on all levels. Hope this helped.
