Notice this twerp said the North American economy, not the American economy. Like I should be happy that illegal scumbag aliens are taking money out of our system and propping up Mexico, El Salvador, Guatemala, et al. By the way, an illegal alien I worked with last year bragged constantly about how he didn't pay taxes. Sure he paid sales tax, but he was an illegal, hired with bogus paperwork, working on a 1099, and sending most of his money back to Mexico.
"How many are stopped and how many manage to cross?"
I don't know how many, but as to how they get across, I say refer to a story I saw here a couple of weeks ago about a tunnel found outside of Tijuana that ran a couple of hundred yards into the US. Don't be surprised if dozens more have been dug all along the border. Why not? The North Koreans have been using tunnels for years to infiltrate the South.
"The undocumented immigrants in the United States - 8 million, according to the National Office of the Census- pay taxes, keep inflation under control, are a cheap source of manual labor for agriculture and the service sector, and sustain economically a population that is aging very fast."
Let's see...they also use up taxpayer resources, spread disease that American citizens are vaccinated against as kids (so I guess we oughta provide these illegal alien scumbags free medical care, too), pervert our education system through this bi-lingual teaching crap, drive on our highways without insurance (again, the scumbag I worked with last year...just guess who'd have to pay if he'd gotten into an accident? Yeah...you), etc. Pay taxes? Yeah right. Sustain economically? What the hell kinda gobbledegook is this? This brain stem already admitted they send 80% of what they make back home. The only economies they're sustaining are those in Central America and Mexico! Manual labor for agriculture? That's easy enough to fix...take these American welfare suck-offs and put them to work in the fields. That would trim the welfare rosters faster than anything.
Sorry, I'm just getting tired of this crap. Our nation is being invaded from the south just as Rome was invaded from the north...and no one seems to want to do a friggin' thing about it. This one's gonna bite us in the a** really soon.
Scouts Out! Cavalry Ho!
My solution for the manual labor is to use the same migrant workers the mexicans use.
There is an Indian population of about 10 million which does not speak spanish. During harvesting season the mexican growers send buses up into the mountains to pick up the Indians and take them to the fields. At the end of the season they are bussed back to their viliages.
