You're welcome to come to Canada or take a trip to the UK anytime you want to see the "benefits" of not-for-profit healthcare. Let me know when you feel like waiting a month or so for a MRI or longer
Well, part of the problem in the UK is successive governments with anti-national healthcare agendas trying to introduce half-cocked "internal markets" and other privatisation-by-stealth initiatives. Last time I had a MRI it was outsourced to a private contractor operating on the hospital grounds.
That's what the current restructuring is about - its supposedly about letting GPs (who aren't government employees) run the system, but since GPs have no idea how to manage a national healthcare system, the reality is that they'll outsource it to big multinational infrastructure companies. The result is a system that combines the efficiency and business sense of government with the humanitarian and social values of big business.
So, really, its a no-score draw: If you can't criticise private healthcare based on the US where its been corrupted by back-door nationalisation, then you can't criticise public healthcare based on the UK where its been corrupted by back-door privatisation.
Personally, on balance, I prefer to get my healthcare from a doctor rather than a salesman, without worrying about whether I can afford it, even if I have to wait a bit for non-urgent treatment.
...and yes, any healthcare system has to make sensible decisions about when to stop throwing money at dying patients. Its not a nice thing to have to do, but no healthcare system has infinite resources - either the money comes from taxpayers or peoples' insurance premiums. Part of the reason why you don't see "pure" free market healthcare systems is people get all upset if people are turfed out on the street to die when there is no longer a business case for treating them.
