And don't forget that will be approximately 30 million or more to add to the welfare roles. Since they are all undereducated and make approx $20k a yr (from an article I read the other day) every single one of them are eligible for EVERY social service available. The federal poverty level is $24k.
One third of illegals are already on welfare, and once on, it's very hard to wean them off. They're getting a free ride. What's not to like? Go back to Mexico, Guatemala, Brazil, Costa Rica? Are you nuts? They'll say we 'owe them' that for stealing their country and vote dem party lines for social welfare programs until the cows come home. The cultural divide between Mexicans and Americans is like the Grand Canyon -- it would take generations to assimilate them, which isn't what they want anyway. (Not to mention the absence of English on their to do list.)
