Taking the USA as an example, all the ethnic minorities are disadvantaged both economically and socially. From the 1920s to 1940s, ethnic minorities (including people of African, Asian and Hispanic descent) moved to the cities in large numbers, where they remained hidden in the lower strata of urban society, struggling simply to survive.
以美國為例，少數族群在經濟、社會上是全面的弱勢，二○到四○年代，少數族群（包括非裔、亞裔、與拉丁美洲族裔）大量集中到都市，隱身於都市底層，為生計奔波。
