During the Industrial Revolution (1760-1890), people began moving to more heavily indstrualized countries. Such as Britian, France and Germany.
The conditions in the factories were bad, workers often lived in cramped spaces. They were also exposed to dangerous chemicals by the machines due to poor ventilation.
It wasn't just the chemicals, the machinery were also dangerous to operate as well.
The Industrial Revolution changed the way people lived by offering more jobs to people. The upper-class and middle-class workers were paid better and as a result, were able to move away from all the poverty.
However, the poorer workers would not get the same work hours or payment as the upper and middle class. Their standard of living had decreased as they needed to work more hours and got paid less.
