The reason they are expected to pay is because they made a choice to come to the U.S. and become a part of that society. If you don't want those implications, don't make that choice. The reason people make the choice is because they want the benefits they may get from coming to the U.S. I realize it is too hard for many that come to the U.S. to become citizens; we need to fix that problem.

But really, if you want to come to the U.S., suck out some wealth, and then say "so long", well, you'll get what's coming to you.
