When Bernie Sanders says healthcare should be a right he is 100% accurate. It should absolutely be a right, just like it is in every other developed nation. Shockingly, these systems work just fine. Nobody breaks into a doctor's home and demands free services. They go to the doctors office, get service which is free at that point of service, and go home. The doctor gets paid, the patient is healthy, the country moves on.
Market economies do not work well for healthcare. Healthcare is an almost entirely inelastic demand. Markets are absolutely horrible at dealing with inelastic demand.
If, as you say, there is a right to life, then their must be a right to healthcare. The best way to guarantee this is with a single payer, free at the point of service system. It is cheaper and works better overall. After all, without a guarantee to life, what other right can we honestly say we have?
This is all little more than a fetishization of 'choice' over the sanctity of health and life. This country should really meditate over which side of that coin they really want to be on.
