The document discusses the Gilded Age in America from 1873 to 1893, a period of immense industrial growth and wealth accumulation by prominent businessmen known as "robber barons", but also rampant political corruption. It describes how under the presidency of Ulysses S. Grant from 1869 to 1877, the national debt ballooned as the economy boomed but scandals like the Crédit Mobilier affair eroded trust in government. Political machines like New York's Tammany Hall, led by Boss Tweed, exploited loose regulations and used patronage systems to entrench corruption at the local level. Despite new prosperity, the rise of labor unions showed growing unrest with the lack of reforms during this era.
