To clarify, Ewing explains how the United States and the colonial society blended together by the successive flow of immigration from all around the globe. But, he also seeks to highlight the attitude of the native population towards international immigrants that change as political policy changes (Ewing, p 2-4, 2012). Meanwhile, in an article called "The Unwanted: Immigration and Nativism In America," Schrag reflects an indisputable argument about the nativism, failed immigration reforms and illegal aliens (Schrag, p-2, 2010). Schrag notes down the reason sometimes immigration becomes a respectable measure than other to shape migrants' life? He tries to make an argument that, immigration is a path that helps immigrants to contribute, adopt and assimilate the culture in the host country along with the financial opportunities they could find there (Schrag, p-3, 2010). The argument seems quite overwhelming and notes that US immigration historically was always an open path for the people to inhabit in entirely new and different society. For example, In 1970's Americans faced labor crisis and millions of African slaves were brought in the United States.
Japanese and Chinese workers were welcomed to work in the farms as well at the time of the labor crisis. Moreover, Shrag argues that, American immigration policy welcomes all the immigrants around the globe when in need to fill the gaps for labor forces but, do not care anymore about immigrants who became illegal even they helped the States to grow economically (Shrag, p-8, Sept 2010). The world views the United States as the melting point of opportunities where all hard work gets paid off, but this hostile attitude towards aliens cause immigration to flow somewhere else where immigrants find the comfort and security. Thus, the opportunity cost for receiving highly skilled personnel for America would be less than before and high to other developed countries like Germany, Australia, and UAE.
