We're talking about the differences between universal systems - where, in some cases (such as Germany, or Switzerland) buying insurance is mandated - and non-universal ones.
And yet, you predicated a number of your arguments on a comparison to a single-payer system.
You're still wrong, though, even if you were just talking about mass uptake of the US system.
Pray tell, how exactly will that reduce administrative costs significantly?
You think the guy who needs to go bankrupt to pay for his heart-transplant cares how many superfluous MRIs he gets?
What, you think I'm claiming that such a patient is who currently drives the use of expensive diagnostics? Don't be silly.
"Hey Joe, sorry your coverage maxed out and you're now going to be bankrupt - but don't worry, the guy in the next ward is getting an MRI he doesn't need". "Hey Bill, sorry we had to deny you coverage because you've developed diabetes - don't worry, though, Jim down the hall is getting this awesome new drug that works slightly better than the generic equivalent."
Appeals to emotion with no logical connection to the point being made.
The "benefits" of the system you cite - more MRIs, flashier drugs - are only benefits for a tiny fraction of the fraction of people who have coverage. Why on earth would you defend them, let alone cite them as reasons in favour of the system?
I did not call them benefits. I am not claiming they are benefits. Nor am I even defending them. But they are features of the system that Americans are demanding. And will continue to demand. You seem unable to distinguish between statements about the way things are from statements about preferences.
Works in pretty much every country that's implemented UHC systems so far. What makes the USA system different?
We're different. Hell, the fact that we're the only ones without such a system kind of proves that point.
It DOES compute. More people covered equals a bigger risk spread
So individual insurance costs may lower. Overall costs? That doesn't help at all.
greater purchasing power and less bureaucracy.
Less bureaucracy? Extending coverage creates
less bureaucracy? No, I don't think so. A single payer system might create less bureaucracy, but again, single payer is not the same thing.
So, the USA are, in the Western world, uniquely incapable of implementing a healthcare system for the same costs as other comparative systems? Why?
Perhaps because we do not want, and will not accept, the same healthcare system as other countries. As I said, we make different demands. Whether or not we are right to make such demands, whether or not it's worthwhile to make such demands, doesn't change the fact that we make such demands and will continue to do so.
But whatever the reason, there is not a single plan that has been put forth in congress which would reduce our healthcare spending to Canadian levels. Nor have there been serious proposals from outside Congress which can realistically hope to accomplish that either. References to the cost structures in other countries don't cut it: nobody can point to any achievable savings
in this country which could bring our costs in line with Canada, unless you're willing to cut services dramatically. Which nobody is willing to do.
