In America, Companies truck Mexican slaves into our country to work (and die) in factories (below minimum wage) producing Spam (and other forms of depressing meat). When the company needs to reduce employment they just tip off the immigration police and problem solved!
I actually laughed at this.
First off, by saying slaves, you imply that they are "trucked in" against their will and forced to work until dead, with no pay. By definition, 'immigrate' means "to enter and usually become established," whereas 'kidnap', by definition, is "to seize and detain or carry away by unlawful force or fraud." This means that our problem is not illegal immigration, but kidnapping. So, you're basically saying companies all over the country are breaking the law on a daily, widespread basis, and you only "proof" is a documentary, which brings us to point two.
Point Two: No matter how compelling this documentary is, it's still a movie, funded by Participant Media, a company whose only goal is to make money. It is not an unbiased study, it's a movie. Act of Valor, The Lorax, Happy Feet 2, all movies with a "message." However, to make that message, they only tell the facts/stories that promote their message. Act of Valor told all those "acts of valor", but didn't show the training, and boot camp, and all those other things that aren't so valorous. Am I saying that the military is horrible? No, they're great, I'm just saying that the movie is not a good reference for the stuff that goes on in the military. 'The Lorax' shows us what we would look like after we cut down every last tree in the world. However, don't you think we would have wised up long before that? They paint the picture to promote their thoughts, but the picture is does not show both sides. 'Happy Feet 2' looks so sad with the hundreds of penguins slowly starving to death, until we realize that millions of animals die every day. Also that penguins can't actually talk. I'm not saying that we shouldn't care about our environment, I'm just saying that movies aren't a good reference.

How does illegal immigration benefit YOU?
...since [illegal immigrants] can't take advantage of welfare, they don't cost tax-payers money...
Except they do cost tax-payers money. Illegal immigrants that end up criminals (not all of them do, but it does happen) cost the police time and money, and, since the police are funded by us, the taxpayers, illegal immigrants cost the tax-payers money.
Illegal immigrants who work for less than others will cost us money, since they take money for jobs we would have done.
Illegal immigrants who go to public hospitals will receive free care, since they can't pay for it anyway, and since public hospitals are funded by the government, they cost tax-payers money.
