This is only true if you are speaking of the controlled immigration of highly skilled, law-abiding individuals. Value in a capitalistic economy doesn't materialize out of thin air, and illegal blue collar workers bring nothing of value with them across the border. Unless of course you're one of those management-types who is pleased because lower wages boost your bottom line.
