What were the differences between the Gilded Age and the Progressive Era?

Answer 1

"The reformers of the Progressive Era advocated the Efficiency Movement. Progressives assumed that anything old was encrusted with inefficient and useless practices. A scientific study of the problem would enable experts to discover the "one best solution." Progressives strongly opposed waste and corruption, and they tended to assume that opponents were motivated by ignorance or corruption. They sought change in all policies at all levels of society, economy and government."

"The reformers (and their opponents) were predominantly members of the middle class. Most were well educated white Protestants who lived in the cities."
