Answer:
Progressives were most concerned about the excesses and abuses of capitalism in the late 19th and early 20th centuries. Some of the key concerns they had about capitalist society include:
1. Income inequality - Progressives were concerned about the growing gap between the rich and the poor, which they believed was being exacerbated by unfettered capitalism.
2. Monopolies and trusts - They were concerned about the concentration of economic power in the hands of a few large corporations or trusts, which they saw as antithetical to the principles of fair competition and free markets.
3. Political corruption - Progressives believed that corporations and wealthy individuals had too much influence over government policies and officials, leading to a breakdown of democracy.
4. Working conditions - They were concerned about the harsh and unsafe working conditions faced by many workers in factories and mines, and believed that workers needed stronger protections and the right to unionize.
5. Child labor - Progressives were appalled by the widespread use of child labor in factories and mines, and sought to regulate or end the practice.
6. Environmental degradation - Finally, progressives were worried about the impact of industrialization on the natural environment, and sought to promote conservation and sustainable development.
