Um... how is it "looting," when Americans are paying them to come here?
It's looting when you sneak in, violating our law, use fake documents (typically obtained via identity theft) to confuse prospective employers, make use of social servies you have never paid for, don't pay taxes or fees or licenses on anything, harbor gang members, encourage underage sex and prostitution as a normal part of your culture, drive drunk and without a license, and trash formerly nice neighborhoods forcing long time residents to adapt of move.
That, to me is looting. The fact that you find some scumbag businessman with no morals to hire you doesn't undo the fact that it's looting.
