The question about "how much" is a valid question and should be answered by each individual based upon resource availability and personal values.
When the decision is made by a third party, be that third party the government or an insurance company, then arbitrary factors must be used to make that decision (i.e., death panels).
That, right there, is the reason why any kind of third party payer scheme is just plain wrong.
I agree.
However.
In any society the wealthy and powerful will receive the maximum possible health care.
All others will be subject to some type of rationing that determines what they will get.
In USA we ration to a considerable extent by price, with those who don’t have insurance being essentially excluded from much health care, and those with insurance being rationed by insurer rules, etc.
In countries with government health care, rationing is generally by availability, waiting lists, wait time, etc. Of course, the wealthy and powerful in these societies generally have connections that allow them to circumvent these restrictions.
My point is that all countries ration health care, the major difference being the mechanism they use to do so.
