hints： Progressivism;Upton Sinclair;Ida M. Tarbell;Theodore Dreiser
By 1900, the United States had seen growth, civil war, economic prosperity and economic hard times. Americans still believed in religious freedom. Free public education was mostly accessible. The free press continued. On the negative side, it often seemed that political power belonged to a few corrupt officials and their friends in business. In response, the idea of Progressivism was born. Progressives wanted greater democracy and justice. They wanted an honest government to reduce the power of business. Books by Upton Sinclair, Ida M. Tarbell, and Theodore Dreiser described unfair, unhealthy and dangerous situations. These writers hoped their books would force the government to make the United States safer and better for its citizens.
