Let me head off greatjustice then "because America's infant mortality hasn't fallen as fast as socialized health countries, that's PROOF we need a libertarian health system".
Infant mortality is
measured differently in the US compared to in other countries. Apples and oranges.
At any rate, I'd say "infant mortality was higher" would fall under common sense; of course it was higher, medical technology in 1960 was vastly inferior to where it is today. See, that's a problem with measuring healthcare systems across fifty years.
However, it is
pretty clear that the increase in the cost of American healthcare isn't proportionate the increase in quality.A Libertarian health system wouldn't have any doctor licensing system at all. So anyone could open up shop and call yourself "doctor". This will improve accessibility for "doctors" and reduce costs. The mechanism that will control quality is that if too many of your patients die, then you won't get customers. So the "free market" will reward those doctors who aren't serial killers. But you'll be free to change your name and practice medicine in another town where nobody knows you as the "granny killer". You could also forge documents claiming you went to a prestigious medical school, since the law against that won't exist under libertarianism.
Any could call themselves "doctor", just like anyone can call themselves King. They couldn't claim to have gone to a prestigious medical school, since that would constitute fraud, which would be coercive and thus a crime. Ratings agencies similar to the Canadian Standards Association and Underwriter Laboratories would crop up, though many
exist in a limited form already.
There will be no form of subsidies like medicare / medicaid. Everything would be up-front payment, private hospitals, or competing private health insurance. There will be no taxes, and no mandated savings for health care or retirement, because those oppress our self-determination to live in the moment.
Costs would be forced to remain low so as to remain competitive, and the poor would be able to receive care through charity hospitals or mutual aid associations. People would not be forced by the government to pay for a "retirement plan" that
pays substantially less than one could get by putting it in a decent hedge fund and has its payout dates changed arbitrarily so that those who enter the system later get paid less than what they put in.
Insurance providers would be free to write the contracts any way they like or exclude sick people from insurance altogether, or have clauses where they can more or less rewrite the rules any time they like, just like credit card issuers and cell phone providers can. Note that it would be part of a libertarian social system, so there would be no food, drug or product standards at all and selling faulty products, misleading advertising and misleading contracts would be entirely legal. If anything adverse happened to you or your family, friendly litigation would ensure justice.
Insurance providers would only be present for the worst of unforeseen situations. Since they would not be forced by states to cover certain things, they would offer far higher payouts for these unexpected circumstances, would have far lower premiums, and would be far more flexible regarding pre-existing conditions (which would now prevent you from getting insurance for that specific condition, but not unrelated problems). They would also have to remain flexible to keep up with competition, which would be far greater when things such as mutual aid and new companies came into the picture. Food and drugs would be regulated the same way appliances are, with competing certification agencies in turn backed up by third parties such as insurance companies. Huge pharmaceutical companies would not be favoured as under the present system, so innovation would increase and cronyism would be reduced.
But if something you buy kills you, it's not the sellers fault, it's you fault as soon as you take possession of the product, you know, since you freely gave your money to that person in a free and fair exchange, they're not liable if it explodes 5 seconds after purchase.
If someone sells you something that has adverse affects without warning, they would be sued, again, for fraud. If someone sells you something and warns you of a certain percentage chance of causing Problem X and Problem X arises, then they would not be sued as you knowingly made the decision.
However, if you were dying of a horrible disease and only Medication X could help you, the government would not actively prevent you from buying Medication X because it has a tiny chance of causing an unpleasant side effect. It would be the decision of the patient rather than a bureaucrat in the FDA.
Also, drugs could be sold with false advertising without any clinical testing (in fact, they could legally lie and claim they tested it, because the law won't exist) and companies would not be held liable if you got sick or died, because those laws wouldn't exist anymore.
See above. Clinical testing would likely be common via third party licensing agencies, not to mention insurance companies (since you wouldn't want to have to make constant payouts because your clients are taking dangerous drugs that you haven't stipulated aren't covered). If you got sick or died, the pharmaceutical company would be held responsible to the victims, not a government agency that would fine them an arbitrary amount. People would not be exposed to the
moral hazard of relying on a single source that they assume is always correct compared to multiple reliable sources that they would double check.
If anything happened to you from using any of these "free market" medical services, they would not be liable, because government enforcement would not exist. But you could take them to court to try and get some compensation.
See above, again.
