Here is an article that talks about how much money is exported to Mexico, they estimate 13 billion.

The first link looks like an opinion piece by a biased source to me, and I don't see any links to any data that indicates any hospitals have closed due to the costs of illegal immigrants. She does make this statement:
What is unseen is their free medical care that has degraded and closed some of America's finest emergency medical facilities, and caused hospital bankruptcies: 84 California hospitals are closing their doors.
But she doesn't actually cite any sources or data, or specifically link the 84 CA hospitals to immigrants. She doesn't provide any sort of quantitative analysis of how services have been "degraded", or who decided they were the "finest emergency medical facilities." I know a lot of hospitals around me have closed, but it had nothing to do with immigrants...it was because the larger hospitals crowded them out, annexed them, or they were shut down by the State.
The second link I'll definitely take a look at at home because most of the sources cited aren't accessible to me through the fartsmilter at work (which usually means a politically biased source as opposed to unaffiliated research center). I'm surprised it's in the billions, but it's certainly plausible considering the # of immigrants both legal and illegal. But you have to track the money further than that. My in-laws in Guadalajara buy groceries at a chain owned by a US umbrella corporation. They shop at Wal-Mart on Saturday just like my wife and I do (well, not if I can help it, but that's another story

), and my FIL buys piles of crap at Home Depot. So a lot of that money comes right back.
Now we have a trade imbalance with Mexico because we've traded the cheap manufacturing jobs for higher-skilled, higher-wage jobs. Mexico is swiftly losing those jobs to Asia, and perhaps that imbalance will shift there in future decades.
Which isn't to say I disagree with your basic premise, in fact I agree with you. I don't think people should be allowed to be here illegally "outside of the system" which puts undue stress on the system. But I think the gov'ts of Mexico (and other Latin American countries) and the US are to blame. The US for not recognizing that most of the illegals are working and filling needs and that the system should work for these people, and Mexico for thinking that their inability to administer a semi-effective gov't which drives their citizens out is somehow our problem. Fox shouldn't be asking us why we don't legalize the illegals...he should be asking WTF is wrong with Mexico that they want to leave in the first place.
