The correct answer to this open question is the following.

The differences between the working class, upper class during the socialist reformers during the progressive era were the following.

The Progressive Era in the United States was a time in US history when people tried to face and solve all the problems of the Gilded Age. During this period, rich families got richer and the working class got poorer. The upper class amassed incredible wealthiness while the working class, on the other hand, lived in poverty and sometimes in extreme conditions. This made that owners of big corporations dislike workers and their fight for better working conditions. Big companies produced food but under unhealthy and unsanitary conditions. This created radical political views, neglecting the protection of the environment, and the increasing problem of overpopulation in the large cities due to constant immigration.
