The document discusses the consequences of Chinese immigration to the United States during the 19th century gold rush. Large numbers of Chinese immigrants arrived seeking quick wealth, with over 300,000 living in the US by 1880. However, they faced significant discrimination, as laws like the Chinese Exclusion Act barred further Chinese immigration for 10 years and denied naturalized Chinese citizens the right to vote or hold state jobs. Unable to find other work, Chinese immigrants took jobs in difficult fields like building the transcontinental railroad and working in cotton plantations.
