In the late nineteenth century, factory inspector Florence Kelly explained the plight of "healthy children" at a conference held in Geneva, New York. As stated in the clippings of the newspaper, "She attracted attention to the fact that we forget the existence of a rich child when we are about to celebrate the birth of Christ." Adolescence Is the beginning of many positive changes in individuals and enabling children to have more time to grow will bring much more benefit than low salary child labor.
At the beginning of the 20th century, child labor was still very common in the United States. For child labor, there was no precedent to work for 19 hours and take an hour off. The National Child Labor Relations Commission hopes to end this practice, but the statistics do not achieve the results they wanted. So in 1908 they asked for the help of Luis Hain and his camera to spread the word. Hine may be the earliest example of investigating photojournalists and documentaries. In the next 10 years, he secretly disguised as children are being exploited. At various times, he worked as a Bible salesman, a postcard salesman, or an industrial machine photographer as an industrial photographer. It is difficult for him to hide the 50 pound photographic equipment When he can not fight the management team, he just canned factory, mining, factory, farm, sweatshop and photography kids when they enter and leave the office I will wait outside.
In 1904, the National Child Labor Relations Commission was organized by a group of reformers to end child labor. They used evidence of child labor using photographs and statistics and thought that child labor reduced the wages of all workers with the union members and these groups considered the state-level politicians Keating-Owen law in 1916 I passed it. This measure prohibits the transport of goods that produce child labor within the province. Three years later, the Supreme Court declared the bill unconstitutional as it interfered with interstate commerce. The same fate was encountered by further efforts of domestic law. Even if the reformers fail at the national level, the reformers succeeded in enforcing the law prohibiting child labor and set the longest time in almost all states. By 1920, the number of child laborers was almost half of that in 1910.
