Why did it take so long for working class people to fight for improved conditions?

workers were simply grateful to have a job and a place to live.
workers accepted that industrialization brought problems.
workers were too tired from their jobs to protest.
workers had no power to make their voices heard.

The correct answer is workers had no power to make their voices heard.

The one element of American society that changed this and allowed working class citizens to fight for better pay, safer working conditions, less hours, etc. was the development of labor unions. The creation of labor unions allowed for a massive organized front that would allow workers to stick together until their demands were met.
