They were more valuable before we had 10% UE. We were at 5 or 6% back then.
Also I see a huge problem with separating families. Many will pick up a gun before they'll send their kids to foster care, etc.
Mining the border, or putting up a 70 foot electric fence, ensures the 12 million number stops growing.
Then we focus on bribing snitches to rat out employers who are giving the illegals a reason to be here. A million or 3 will leave on their own at that point.
So already, I can deliver a solution to freeze that 12 mil number, then start shrinking it thru them walking their asses home... no deportation proceedings needed. That solution does more than Palin, mccain, obama or biden have given us... and it doesn't violate ANY american rights, like that POS AZ bill that you guys love because it aint your asses in cuffs...
