Two factors seem significant: first, relatively porous economic, political and educational arenas that allow immigrants entry to these key areas of American life. Despite the discrimination and poverty that immigrants often suffer initially, barriers to economic and political participation are relatively low.
看起来有两个因素非常重要。第一，美国的经济、政治以及教育领域相对宽松，允许移民进入这些美国生活中的主要领域。尽管移民一开始会受到歧视和贫困，但是经济和政治参与的壁垒相对较低。
