I was thinking more in terms of using it to deny them entrance. In other words, if they're not healthy, we don't want them. Didn't that used to be the case? And I think that even guest workers should have to have a sponsor who is willing to be responsible for them during the time they are here. That would put a little much needed heat on those who employ them.
I really think the Mexican government should have to come up with a fund of some sort. I also don't see why employers of guest workers or whatever they are finally called shouldn't contribute to a fund that would cover emergency care. That way, even if the employer was a small employer that couldn't qualify for an employee health plan, the costs wouldn't be borne by the state or county, as they are now. However, it would not be so expensive that it would drive the employer out of business.
Of course, exactly how we'd go about doing that legally, I don't know. But then I haven't seen any details on how any of this is going to be done.
