Wow.. modded troll.. my first ever troll categorization....
Anyways, while I generally do not mind my taxes going to help people in emergency rooms, at the same time, I would prefer that people who can afford it, not use my taxes.
And really, is it that much of a deal to expect people visiting a foreign nation to have sufficient funds or credit (or debit card preferably) on record that shows they can afford to be in the country for whatever reason. I am not advocating that the information be stored and used by the gov, or any entity other then your own financial institution, but is it really that big of a deal.
Granted the examples I used earlier, probably sucked, I will admit that, I am at work, and commenting here is not exactly that high of a priority where I will sit for an hour trying to word out a witty and useful comment.
The point remains the same though, people visiting should be able to prove in some way they are financially stable as to not be an anchor on the country they are visiting, USA, or other countries.
