"wetbacks", "demonizing", "criminals" C'mon guys, it's economics, complex economics that benefit and hurt the U.S., and the net result is hard to quantify. That's why we have had unchecked illegal immigration for decades.
I feel the main threat to the average white guy is not economics, it's cultural. Yes as a Mexican born and raised in Mexico but living in the U.S. for 30 years, I see how communities of immigrants are changing the landscape... for the worse... It's rather easy to tell the predominant ethnic group living in an area by the looks of that community.
