Well there's always Switzerland, they have some incredible medical treatments. They wouldn't mind us sponging, especially since we do pay our own way. Or any of the other westernized countries with modern medicine. Just like other countries send patients here for medical procedures and treatments that they don't offer. It's a small world now, and reciprocity is an understood concept.
But really the fact is regardless of the style of medical care or health system offered, because the US is a large, educated, wealthy, populous, first world nation, it will always be a natural aggregate point for advanced medical techniques.
It doesn't matter how you pay for it, in the end medical advances will continue.
I don't begrudge those citizens of the US that lie to get Canadian health care (sometimes for things as simple as the flu). I do sincerely wish that there were better options for them. I suspect a lot of Canadians think like that.
I was wrong when I said I'd be laughing two years later, that was cruel and I'm sorry. The reality is I mourn all unnecessary deaths.
