We tried unregulated healthcare - it was a disaster. The FDA prevented a Thalidomide tragedy in the US.
Bit of a strawman there. I haven't argued for complete deregulation. There is virtually no market in the US which is has no regulation. I am arguing to remove regulations regarding what kind of insurance people must have, remove the tax subsidy for health care insurance, and allow a market to develop where people are directly responsible for a larger fraction of their health care expenditures. If you want to give poor people money or vouchers to spend on health care, that's fine. A free market doesn't have to mean that poor people lose out. In fact, if I had my druthers, they would gain, as would everybody else.
The two examples you have given (the car industry and the semiconductor industry) are industries that do have significant barriers to entry.
And yet, they are free markets with healthy competition, where consumers have been seeing quality-adjusted price drop dramatically over the years.
Your argument is silly.
An unscrupulous doctor could easily state that unnecessary treatment is needed just to get the money. They could recommend more expensive treatments rather than what they'd consider the best choice.
Easily? No, I don't think so. How would an unscrupulous doctor do that? It's far easier for an auto mechanic to rip you off on the repair of your car. For all you know, he purposely breaks something during the inspection. Is your unscrupulous doctor going to give you syphilis while he's examining you?
A dentist in my town was recently struck off for stating that patients needed fillings when they didn't - it was a nice little earner for him. The patients had little idea about that.
Well, it sounds like he was found out. Hopefully, in a free market, such dishonest providers can be ferreted out quickly. They're certainly more likely to be found out in a free market where people exchange information freely and prices are lower (easier to get a second opinion).
If I buy a house from someone and they have mislead me I can sue, depending on contract law. If a doctor gives me bad advice and I die, I can't sue.
You can't sue? Are you kidding me? Well, maybe not you if you're dead, but your loved ones and dependents can sue. Medical malpractice lawsuits are very common in the US. Too common actually.
Read the real-life example that Emily's Cat gave
You and Emily see that as a rebuttal to my claim. I see it as supporting evidence. Four weeks is plenty of time to make good decisions. It is just that the primary decision she had to make, which consumed all of her emotional energy, dominated all the rest. This isn't usually the case, nor is it the case that you're all alone (as she was perhaps) in making all these decisions. In a free market, you would probably see a health care concierge service industry pop up. If that existed, Emily could have offloaded some of her decision making to a 3rd party who was acting as her advocate.
A smartphone, however, will meet minimal standards of functionality, and you can change it after your contract has expired, or upgrade beforehand or simply buy another and they all probably cost less than a single trip in an ambulance in the US.
There are plenty of situations where they are. And the most important ones are the ones where bad decisions aren't reversible.
You're still trying to conflate very specific dire situations, which at best represent a tiny percentage of health care spending, with health care in general. And in a free market, professional services will arise which meets the demand for quality, 3rd party advice.
I am struggling to be polite here - but that isn't how most humans behave when they or their loved ones are under mortal threat.
You're now the 3rd person in the last day in this thread to use this passive-aggressive language. Here's a hint. It is impolite to say that you're struggling to be polite. So, you may as well cut the crap and be impolite. I'm not giving you credit for being polite anyway when you speak that way.
Early treatment tends to have a better prognosis and cost less. Preventative treatment often is even better.
Studies have shown that preventative health care usually costs more in the long run. Yes, there are special situations where it saves money, and in those situations (where there are positive externalities), it makes sense for the government to subsidies its provision (e.g. vaccinations). For the vast, vast majority of health care spending, there are no positive externalities.
Someone could work with a bad back but be less productive.
Coulda woulda shoulda. If you start subsidizing bad back treatments, you could also end up with double or triple the number of people claiming to have a bad back.
Someone could have TB and be unable to afford the treatment. Whilst they are slowly dying, they are infectious and they could infect many other people. Some of these then use the unregulated free market and buy a long course of antibiotics to treat the disease, but because of the lack of oversight, the bacteria has developed immunity to that antibiotic (and indeed most other antibiotics). Again, we have a model for this - India and the rest of the Indian Subcontinent. It has a sufficiently large middle class (>200-million) for there to be a market in healthcare but little effective regulation.
Under your proposed system, it would make sense for insurance companies to employ people to specifically find (spurious) reasons why treatments shouldn't be paid for. This is one thing that the ACA addressed.
The claim that insurance companies are finding spurious reasons to avoid paying for treatments is largely a myth. My personal experience is that insurance companies are big bureaucracies which follow protocols diligently, and as long as you dot the "i"s and cross the "t"s you get what you're entitled to. Unfortunately, there is a lot of fraud and selection bias in the system, so insurance companies have to be vigiliant to keep premiums for honest people affordable.
People with preexisting conditions, or family histories, presumably should just find the most comfortable way to die in your preferred system.
More disingenuous, emotional rhetoric is not a good substitute for argument. Regardless, doing something for people with preexisting conditions is a separate issue from the best way to set up a health care market. If people have conditions which make their health care expenses unaffordable, then perhaps charities or the government should step in and subsidize their health care. Forcing insurance companies or hospitals to lose money on them is just a way of sweeping their costs under the rug and making other health care consumers pay those costs implicitly. Politicians of course like doing this because they don't have to raise taxes or cut spending elsewhere to provide subsidies for those constituents. There's nothing a politician likes better than replacing a tax hike with a little extra regulation, even though the effect on the taxpayer/consumer is the same.
