Before the Industrial Revolution which began in the late 1700s, people lived very rural lives. Rich landowners were very stingy as always and enclosed their land just to keep away from peasant farmers.
The capital invested in enterprises such as railroads and factories. Because of this, there were more jobs for people and transportation to get them to their jobs.
Due to the production of more industries and many more job opportunities, there was rapid urbanization. Many families from the country side were now moving to the city hoping for a better lifestyle.
When the families moved into the city, they had to live in small tenements. Many people weren't able to pay rent, resulting in having roommates in such a small unhealthy and unsafe condition. This situation portrays inequity because people in the middle class can afford to live somewhere more efficient without having to split rent. In fact, after so many working class people moved into the city, the middle class starting moving out to the outskirts of the country to get away from the overpopulation and disease in the city.
Communism was heavily portrayed. This also adds to the idea of inequity. Employers hired people at whatever age they wanted, not considering risks they would have to take. The working conditions were unsafe. The employers did not have to live through what the workers did day by day. Employees went without food, water and breaks just for little to nothing income.
Because of events such as injuries from work, wanting less work hours and better pay, labor unions were formed. The labor unions ended up winning the right to bargain for and about these things with their employers.
