The Library of Congress

In the early 20th century, the United States entered the era of peace, prosperity and progress. In the growing cities of the country, the factory production volume has increased, the small and medium enterprises prosper, and the income is increasing. As the job and high salary promises attract more and more people to the city, the United States began to turn to cities of city residents. By 1900, 30 million people (30% of the total population) lived in this city.

The mass migration of people to the city has made some people enriched, but it caused serious problems for others. For emerging middle classes that benefit from increased revenue and leisure time, this expanding city offers many advantages. Department stores, chain stores, shopping centers appeared to respond to the growing demand for cash products. Parks, amusement parks and baseball stadiums are designed to meet the needs of aesthetic needs and entertainment. As with general infrastructure, the transportation system has been improved to respond to the growing needs of resident ocean resident.

Thousands of poor people live in cities. Fascinated by the hope of prosperity, many rural families and immigrants from all over the world will work in these cities. By 1904, it is estimated that one third of people living in this city are in the hunger. For many urban poor people living in cities leads to a decline in the quality of life. Because there are few available urban services, the working class lives in overcrowded conditions every day with inadequate water supply facilities, unpaved roads and diseases. In the far back of the middle class, wages of the working class only offer self-sufficiency life and there are few opportunities to escape from the slums of the city.
