Actually, a lot of them do. But we're making it difficult telling them daily that they're "illegal". So we not only physically make it difficult to assimilate, because they must hide in the barrio lest the Border Patrol snag them, but we're also giving a bad example of what it is to be "American". Which from their vantage point looks like a bunch of tight fisted bosses and people reminding them that they're "illegal" and not wanted here.
All the above needs to change.
America was built on the rule of law not men. That's what set us apart. I'm not willing to live under their system (rule of men), and they'll learn about our system (rule of law) by getting their butts kicked back over the border.
They need to be reminded daily that they're here illegally, just as small business owners are when they play by the thousand rules govt. set up for that purpose. Like taking out for taxes. The illegal business men (rule of men) are hurting the rule of law businesses.
I could go on. You're just wrong on this.
