Immigration is in America's Self-Interest

It is true that immigrants work when they get to America. They get jobs as soon as they can, and yes, they’re willing to work cheaply. But they don’t steal jobs. If you’re paying the teenager who baby-sits your children $15 an hour, and the girl across the street comes along and says, “I’ll do it for $10,” has the new girl stolen anything when you hire her? Of course not. It’s your money. You have no obligation to pay a higher price, if you can get the labor for a lower one. That doesn’t change when the nationality of the cheaper babysitter happens to be Mexican. As long as the money that you worked for still belongs to you, you get to choose what to do with it.
