I didn't say anyone said "no cost". The wording I used was "hidden from view" and "no direct cost" meaning no cost at the point of sale. This has an impact on who is paying and impacts choices on what services to get.
There are several different lines of discussion going on, one of which was that it doesn't really cost $5,000 a day much less $30,000 a trip to fly someone helivac someone. $5,000 a day is definitely low, $30,000 a trip is probably high. But some issues: The purpose of insurance is to spread the cost based on the low probability and frequency of using the services. While I agree that the cost is inelastic, it is only mandatory insofar as we have decided it is. But as the anecdotes people have posted in this thread show, if the cost hits you directly, the services become very, very voluntary. Socializing the cost - removing it from the point of sale - allows us to pretend we can pay whatever it costs, but that is only pretend and that is part of the reason why the cost is inelastic. We're lying to ourselves about the cost when we do that, we make it more expensive by doing that and ultimately that is going to come back to bite us, as I'm discussing in another thread. We have chosen, for example, to make health care/insurance more mandatory than police protection in some contexts. And based on Europe's lead, we're going to go further down that road. Eventually we will either go bankrupt or we'll have to start deciding that total healthcare isn't quite as "mandatory" as other government services.
However, much of that is off topic because while I believe that some of the cost of ambulatory services should be borne at the point of use in order to deter abuse, the real cost of the service is so high, use so rare and jurisdiction so broad that most of it should be administered by government via taxes. We had a similar thread about voluntary fire department fees and I am against that concept as well.
That goes against my moral beliefs, but sometimes in politics my pragmatism > my moral beliefs. This, I strongly disagree with. As the anecdotes show us and the logic tells us, nationalizing the healthcare makes some contributors to the problem worse, in that eliminating the direct cost reduces the incentive to self-triage and encourages abuse. By the same token, making healthcare non-profit will help, but as with many discussions on corporate profits, I think you are overestimating the impact of that. Regardless, if we lower our costs by 20% but don't fix the rising cost trajectory, it will remain too expensive and just be worse again in a couple of years.
And "better" is, of course, a matter of what you measure and how. Logically, if nationalization doesn't change the quantity and quality of doctors, ambulances and hospitals, all it can really do is even-out the level of care by rationing it. I don't understand why people overlook this Law of Conservation of Doctors as I will henceforth call it.
For example, one of the primary measures that people have of "better" is, as you noted, fewer people uninsured. But the Law of Conservation of Doctors requires that if you provide a doctor for someone who didn't used to have one, you have to deprive someone who did. This manifests as substantially longer wait times for treatment in many countries with socialized medicine. You increase one person's access to a doctor and reduce another's. That's "better" for one, "worse" for the other.
