Nativist objections to Chinese immigration to the U. S. took many forms, and generally stemmed from economic and cultural tensions, as well as ethnic discrimination. Most Chinese laborers who came to the United States did so in order to send money back to China to support their families there. At the same time, they also had to repay loans to the Chinese merchants who paid their passage to North America. These financial pressures left them little choice but to work for whatever wages they could. Non-Chinese laborers often required much higher wages to support their wives and children in the United States, and also generally had a stronger political standing to bargain for higher wages. Therefore, many of the non-Chinese workers in the United States came to resent the Chinese laborers, who might squeeze them out of their jobs. Furthermore, as with most immigrant communities, many Chinese settled in their own neighborhoods, and tales spread of Chinatowns as places where large numbers of Chinese men congregated to visit prostitutes, smoke opium, or gamble. Some advocates of anti-Chinese legislation therefore argued that admitting Chinese into the United States lowered the cultural and moral standards of American society. Others used a more overtly racist argument for limiting immigration from East Asia, and expressed concern about the integrity of American racial composition.
