Why is your only argument for this the cost? I get it. It isn't as costly. That shouldn't mean that it is the only option available. That's the point I make that you refuse to hear.
Because that's the one Dan opened with - objections on cost grounds.
You'll note from the links I already provided that socialised systems also provide better mortality rates. But yes, you're right, the USA does have more MRI scanners per capita. On that metric, you have the greatest healthcare system in the WORLD.
Give me another option. There are, as best I can see, only 3.
1) No socialised healthcare at all.
Each to their own. Without some form of socialised provision, the needy die. This is simply unacceptable. On this, I hope we agree.
2) Socialised healthcare for some
With patchy socialised provision, as the USA has, it seems that the patchiness contributes to the costs and the poor levels of health generally. Again, I hope we can agree on that, as that's what the statistics seem to bear out
3) Socialised healthcare for everyone
The levels and manner of provision will vary from system to system, but in general these types of systems are borne out in practice as cheaper and more effective. They are also more morally sound, as they do not allow people to die, suffer or face financial ruin from preventable causes simply due to lack of money.
Is there another I've missed? Although you have made some mention of "alternatives", there don't logically seem to be any...
