How can Migrant Imaginaries speak to anti-immigration/migration sentiment?

I think Migrant Imaginaries has a lot to offer when looking at immigration sentiments. I find it important to know some of the history between the United States and Mexico in order to better understand some of the issues at hand. I feel many forget that at one point in time, part of the U.S. was a section of Mexico. Much like the Native Americans, the Unite States expanded and pushed out Indian tribes, diminishing some of their culture and claiming their land as our own. We also did the same when expanding the U.S. over parts of Mexico but one difference between Native Americans and Mexicans is that in present time, many still see the Native Americans as being the indigenous inhabitants of North America. People seem to have forgotten that a decent proportion of the South-Western United States was Mexico, making those from Mexico one of the natural inhabitants of the U.S. as well.
 I also think the book also makes a great analysis on the economical relations between immigrants and the labor that they endure here in the U.S. When looking at the labor movements of the past 100 years, we can have a better grasp on the history and politics of the subject in order to better understand some of the immigrant issues that are occurring in the present day.
