Less than the 800 billion or so we spent on other crap recently. Plus it would have made direct jobs. Probably a few billion at most. Illigal immigration cost California 10 BILLION a year according to this. http://usgovinfo.about.com/od/immigrationnaturalizatio/a/caillegals.htm So it actually saves money and creates jobs. win win.
There probably isn't a child-psychologist, family court judge or half-decent CPS worker who would support this just from a developmental standpoint. And as a taxpaying taxpayer who pays taxes, I don't think my tax dollars should go to supporting illegals kids when we can't take care of our own kids or are schools or failing, cuz taxes are high enough already and our schools are failing, taxes! What if all these minority kids want to go taxpayer funded public colleges with affirmative action programs and minority scholarships? That's a whole lotta back-bending for accented minority outsiders.
