Because compulsory schooling began in part to "prevent immigrant's values from corrupting American values", some critics see its origins as smacking of ethnocentrism.
Ethnocentrism is the demonstration of judging another culture in light of biases that are found in qualities and benchmarks of one's own way of life. Ethnocentric conduct is to judge different gatherings with respect to the previously established inclinations of one's own ethnic gathering or culture, particularly in regards to dialect, conduct, traditions, and religion.
