The definition of work changed by the 1900s because America went through an industrial revolution. It completely changed society and also changed the concept of work.
Before America was mostly a rural country and people were used to work on farms and they used to live in small cities. With industrialization, people started to move to big cities, where the industries were located. Work became restricted to industries, people had terrible workplaces, they endured long journeys of 12 hours per day of work.
