If there are cheaper ways of providing healthcare, what would have to change in the US to implement it?
For example, if there are three hospitals in a region, and they worked out an agreement among each other to not have overlap in specialized equipment (where hospital A sends all MRI patients to Hospital B just down the road), this is currently illegal (anti-collusion laws).
Another example -- a patient comes in with a headache. Well there could be a number of potentially fatal conditions that could be the cause, and due to liability reasons, they have to run tests to rule these out before giving the patient an aspirin (yes, this is an issue, in lower-income areas people go in for non-emergency issues that most likely doesn't need a doctor).

This will never happen in the US, however, because the US is obsessed with concentrating power in private enterprise and refusing to fund social services. We have more than enough money to ensure the health and welfare of all of our citizens. We just don't actually care to do that, and would rather have rich companies and uneducated, sickly, indebted people.

As a Canadian, I gladly fork over a few thousand a year to avoid tens to hundreds of thousands in one sitting should something horrible happen to mine/my family's health.
Not the people going to hospital thing - that happens all the time. It's just that nobody is ever charged thousands of dollars for it.
