I know that in Canada, if I am sick, I will be looked after. I won't go bankrupt trying to pay for my treatment or trying to pay for the legal bills in a court battle, trying to get my insurance company to pay out.

The American system is so truly and completely fucked, I can't understand why anyone would defend it. Better hope you've got good genetics, good luck and a good lawyer. If any of those things isn't in your favor, one quick illness and your financial life is over.
