The problem is that it
is different. What other industry sells a product that you might need in order to survive or to not be disabled which requires the dedicated efforts of multiple professionals with a decade of post-secondary education? What other industry sells a product that you might suddenly need at a moment’s notice that is the only way you’ll survive the day, that requires sophisticated equipment, dedicated facilities, and a team of the aforementioned highly educated professionals?
Most industries are either optional things you want to have but can live without, or necessities you need on an ongoing basis that need more than a few minutes of individual attention.
There’s a lot more to medicine than emergencies and lifesaving treatments. But I think those are the original sin from which the rest flows.
The basic question is this: should people be left to die if they have a sudden life-threatening event (heart attack, hit by a bus, shot) and they can’t demonstrate an ability to pay for treatment? (Note, not the same as not being able to pay for treatment. This would potentially apply to a rich person who got mugged and left for dead, for example.)
Few will answer “yes.” And everything else flows from the “no.” The US’s universal health care system is built around it. We pretend we don’t have universal health care, but we do. It’s just tremendously shoddy and weird. The one place with universal care is the hospital emergency room. Those have been required to treat everyone regardless of ability to pay since 1986. Once you start doing that, the rest flows from there. People start saying, what if it’s not critical to survival but they’ll be crippled without it? What if it’s life critical but there’s time to verify payment?
Can we do better without removing that? No doubt. But we’ll have a hard time getting to a proper competitive market.
Other industries with these characteristics (police, firefighting, rescue, ambulance if you count that separately from medicine) are usually handled by the government or at least contracted by them.
