How Progressive Was the Progressive Era?

The progressive era, in my eyes, could be considered very progressive but at the same time not progressive. Reason being because workers had to suffer and fight very hard for their rights they were still able to obtain some.
Before the Progressive Era occurred working conditions for laborers were very difficult to deal with. Workers worked long hours even during harsh weather conditions, just so that they can earn less then what minimum wage is today. I just finished reading the book The Jungle. The story was about an immigrant family who comes to work in the United States but it speaks of how hard it actually was for the family who represented the lower class trying to survive in a capitalist society.
Although it was just a book it was based on how it was for the working class during the time of the progressive era. In order to recieve more rights many citizens of society had to fight and some even lost their lives.
