PrivetName: we aren't giving away the country to Mexico, the citizens of the US have given the country away to the Oligarchy. Your anger is misplaced, you are blaming the victims of US's Government Kleptocracy instead of the kleptocratic oligarchs who destabilized the Mexican economy by flooding them with the cheap US corn. If you don't like Mexican's illegal immigration, don't blame the immigrants who are looking to survive and get jobs, get mad at the ppl and structures that cause them to immigrate. If you don't like American corperations undercutting US workers by hiering illegals for less than minimum wage than organize to push legislation that would harshly punish the corporations for hiring illegal immigrants for less than minimum wage.
As is, the laws in the US serve to punish illegal imigrants for working more so than the people who hier them for less than minimum wadge, and thoes same corporations are known to call INS to get their own illegal workers deported after the work is done, so they can avoid paying them altogether at times. An interesting book that goes over that government construct is "Reefer Madness: Sex, Drugs, and Cheap Labor in the American Black Market" by Eric Schlosser; among other things, it goes over how illegal immigrants are used by corporations in the US.
Side note: My college wasn't Marxist btw.
