Why not ??
What if someone is getting a deadly sickness like cancer in the usa and he has no sickness insurance
What does this person do wait for his death or that someone throw money to his feets so that he can get some medical treatmeant
This is going to sound kind of harsh...
But if you can't afford medical treatment.
And you are unable to inspire other human beings to contribute to keeping you around...
Then what are you doing that is worth the government stepping in and paying for your existence?
I live by that rule. If I ever get to a point where I am not able to buy food, and no one is willing to feed me - then I will starve to death while digging my own grave (because I don't want to be a jerk and stink up some alley way). If I get sick and cannot afford the treatment, and no one wants to help me out - then I die. Plain and simple.
The other reality is that 5-year survival rates for most of the medical treatments (from cancer treatments to bypass surgeries and other such things) is roughly 50%. Not statistically different from lifestyle change therapy, alone (which can be done at a far more affordable cost). I was born 2 months premature; I 'died' multiple times during and after birth. I 'drowned' at least once in my life. Death has had plenty of opportunities to take me. I've no illusions that it will do so when it is ready - and welcome the challenge of whatever existence rests beyond.
