After enclosure of many farm lands urbanization brought people to the cities because of promises for more jobs. The working class had to work long hours in unsafe job conditions for extremely low wages.
If workers were injured in the factories the proletariat would lose their jobs because of high demand for high speed product from the assembly line. In the assembly line since all the tasks of creating one product were split between each worker had to move quickly. Since the working class, would not be compensated for their injury while on the job, they banded together and made mutual aid societies to support the factory injured workers.
The workers lived in crowded tenements. In the slums they were forced to live with other people they did not know while the middle class lived privileged lives with their family in bigger houses.
Due to the unsanitary conditions in their homes the standard of living for the working class was unsafe for everyone. The people that lived in the tenements were exposed to a lot of illnesses that spread to their main water source exposing the working class to other diseases like cholera.
The based on the ideas of cult of domesticity, middle class women were able to stay home while the working class women went to work because they needed the money to support their families.
Inequity, being unfair has been a leading enduring issue throughout the industrial revolution because the working class suffered while the middle class lived overly privileged lives. Like in the streets of the proletariat their streets were covered in dirt, from dead animals feces also caused illness to spread quickly. For the unfair treatment some people believed in communism, which is the struggle between the middle class and proletariat as unpreventable.
