/kloc-At the end of 0/8th century, many countries such as the United States and Europe gradually developed from capitalism to imperialism. In order to stimulate the rapid economic development and extract more surplus value, and to maintain this high-speed capitalist machine, capitalists constantly exploit workers by increasing labor time and labor intensity.
In the United States, workers have to work 14 to 16 hours a day, and some even as long as 18 hours, but their wages are very low. They know that the only way to survive is to unite and fight against capitalists through strike movement.
The strike condition put forward by the workers is an eight-hour working day. 1877, the first national strike in American history began. The working class took to the streets to demonstrate and proposed to the government to improve working and living conditions, demanding that working hours be shortened and an eight-hour working day be implemented.
