>> No hope at all? If I were underinsured or uninsured, I would still have the option of working to get the insurance I need. If I couldn't afford it, I could still ask others to fund me if they were feeling charitable. Overall, there would still be options. Lack of wealth is not an insurmountable barrier.
What if you had a disease that left you unable to do that? Physically, mentally? You can't work, you don't know people, now what? Why should society deem that life not worthy of saving because of an illness and a bank account balance? It's not civilized. Why should these people depend on the charity of a few individuals and not distribute that burden across society as a minimum guarantee?
>> One of the main problems in the US is that there isn't a clear way to compare health insurance policies.
IMO it doesn't make sense to. You can't know what kind of disease you'll get or when. How can you choose to exclude cover for a broken leg? Are you planning on walking extra carefully, or buying special boots? And why settle for a 90% plan to prop up the health insurance industry when you can give everyone the 100% deal?
>> Your point about Canada is only worthwhile if another country exists where you want to be treated.
The way I see it, it goes one of two ways. (1) everyone has socialized medicine, the doctors are equally distributed but you can still find them [no passionate doctor worth their salt will just pack their bags up rather than treat everyone] or (2) one or more countries exist where they congregate due to lack of socialized medicine, and you're free to travel there if you find the home country offerings unsuitable.
Also, many of the best hospitals anywhere in the world are in Germany, Hong Kong, Singapore, etc.
>> The US subsidizes everyone research on behalf of all people in other countries.
The US government subsidizes the research heavily (as do foreign countries) it's not re-invested proceeds. [1]
