How might the anti-immigrant arguments of wealthy nativists have differed from those of less-affluent nativists?

America is completely composed of immigrants. Immigrants have been exploited for their labor and has been used as scapegoats for problems that arise in the country.

The anti-immigrant arguments have been from nativists or racists where they ignore statistical analysis of populations and the contributions that immigrant labor has brought to America, including the wealth and productivity of the country, the tax base and the welfare programs, and the educational system.  An example of such  racial discrimination is of Mexican and Latino immigrants who make up about a third of the country's immigrants.
