* Herra Tohtori dives into the maggot container
The crux of the question is this:
Should human suffering be allowed to be exploited and turned into multi-billion dollar business, or should the government take care of reducing that suffering on a non-profit basis (ie. paid from public funds simply because it must be done, not because it's profitable)?
Personally, I think something like healthcare belongs firmly in the public domain of economy and should always be mainly funded with tax money.
On the topic of black and white capitalism versus socialism that is always dragged into this sort of conversation... in my opinion, private sector enterprises work perfectly fine in cases where the interests of the consumer and the interests of the business do not conflict as harshly as they do in the healthcare business of US of A. Like, say, buying a car or a computer. Hell, considering Microsoft's operating systems I shudder to think what an operating system designed by a governmental committee would be. So yes, in some cases I do think private sector can do a lot better job than public sector would.
However, this only works as long as you don't desperately need car or a computer. When a statistically significant portion of the populace desperately needs treatment, making them pay for it is tantamount to extortion, and to my view point that is exactly what the insurance companies try to do. From a business stand point, it's just numbers of course. Which is exactly why things like healthcare should not be about numbers and profit, but getting the job done.
Maybe the reason why so many people abhor taxes is because they don't like paying other people's expenses, as they think of it. However, this kind of thinking fails to take into account that statistically it's not entirely impossible for them to be in a bad situation. Like catching some illness or other, and the treatment being more costly than what their insurance covers under the small print... then they can't get the treatment, lose their health, lose their job, lose their life. Whereas if they had been paying for NHS in taxes while being at work (and not paying for a crappy health insurance, so its plus minus zero), they would be getting their treatment statistically much more likely than with a private sector, insurance-dependant system.
Note that public healthcare does not rule out private healthcare sector or additional health insurances. What it does rule out is people not getting treatment because of their inability to
pay for it.
