> you've removed a lot of the flexibility that would have allowed your system to make more of the good if lots of people wanted it

Only if they were capable of paying for it as well. That is a big assumption for something as expensive as healthcare.

I personally find it very comforting that (at least at in principle) both the rich and poor wait in the same line.

>I personally find it very comforting that (at least at in principle) both the rich and poor wait in the same line.

That's rarely the case. For stuff like consumer goods (ie. getting the iphone on launch day, a few years ago) the rich person can buy it off a scalper, or pay someone to stand in life for them. For healthcare they can just fly to a private clinic.

>pay someone to stand in life for them

Recently I learned you can even do this for the DMV... Truly the only place where men are made equal is the porcelain throne.

There’s a lot of ways in which the cost of healthcare in US is inflated due to restrictions and monopolies. Don’t form an opinion on the premise that healthcare is intractable expensive.

Also, keep in mind that the current U.S. health insurance system is a by-product of the government trying to control the price of labor.

> Economics 101 often fails to convey the crucial fact about rationing: under any rationing system that isn't a pure random lottery, the only effect of rationing a good is to change the currency in which that good is priced. [1]

Isn't it often worse than that? Unless rationing can be perfectly enforced (e.g. require consumption of the entire resource under observation of enforcers, which is actually most tenable with housing by frequently checking to make sure only the authorized people are present) then secondary grey/black markets form when there is an opportunity for arbitrage.

> People often mistakenly think that if the price of a good is opaque, then the good must not have a price. This is incorrect. What's more, if you believe it, then you're almost certainly getting over-charged. And very unfortunately, this mistake tends to be most common among less sophisticated folks — who are the very folks that rationing was intended to protect in the first place.

Note that this is one of the problems in the US too. Health care prices are pretty opaque, it definitely has a price - which you'll find out after you get something done, and I would argue people get overcharged - evidenced by the fact that insurance companies can come in and slash the bill to a fraction of what it was (literally saying "you aren't allowed to charge this much").

> What makes dollars unique is that if you inject more dollars into the free market for a good, then ceteris paribus, you will cause more of that good to be produced.

Markets don't actually work this way in practice. That's the theory, the theory rarely actually pans out. We could look at US healthcare, which is an insane mess, but it's pretty easy to argue that it's not actually a market due to insurance and opaque pricing and all the same problems. We've kind of got the worst of all worlds over here. But dental and vision care, which are closer to real markets don't actually work any better. They're still expensive, in accessible, and pretty non-responsive to price signals.

Instead, take something like food, where it's a commodity. That's a place where markets should be the cleanest and most responsive to price signals. We produce 1.6x the amount of food the world needs. And food is some thing where there's a literal cap on the ability of any individual to consume it. Our stomachs are only so big, there's literally only so much each of us can consume in a day. By market theory, prices for food should be almost negative and no one should be with out food given those facts. But that's not how it works out. As always, there are too many confounding factors and the profit motive causes rent seeking at every layer.

By market theory, there should be over production of food, which should cause everyone to have food and food producers to drop out of food production until prices rise to equilibrium where everyone has food and the people producing food have a good living.

Has that happened anywhere? No. Instead, you have corporations standing between producers and eaters finding ways to make food more expensive through value add and marketing. You have producers struggling to get by, buried under a mountain of debt, and often effictively in indentured servitude to the processors. And you have hundreds of millions of people food insecure, tens of millions even in a rich country like the US that massively overproduces food. Because markets in real life don't work according to the theory.

And that's why we can't just approach economic problems with the idea that we can just throw more markets at them. And why we have to think about when systems like single payer, for all their faults, are better than what we'd end up with through markets.

Trust me, if you'd ever had to deal with the American health care system, you would long for the Canadian one.

> Instead, take something like food, where it's a commodity. That's a place where markets should be the cleanest and most responsive to price signals.

There are a whole lot of distortions on every side of the market for food which interfere with a properly functioning market. There are incredible subsidies paid to farmers to produce specific things (which then cause over-production in those items). There are tariffs to protect privileged farmers. There are actual import and sometimes export quotas. Then, rich countries dump the over-production as in-kind food aid to poor countries undermining poor farmers there.

Case in point is Nebbia v. New York[1] where the supreme court affirmed state interference in free markets by setting a price floor on milk to protect a select few milk producers.

Going back to my first comment. The mechanics are clear. An effective price ceiling leads to too few units being offered relative to the units demanded resulting in perpetual shortages and non-market mechanisms end up determining who gets the benefits of the existing units. Persistent price ceilings lead to chronic reduction in investment producing the thing.

Similarly, effective price floors (minimum price of milk, minimum wage etc) lead to too many units being offered to the market leading to persistently wasted productive resources.

Both reduce the total productive capacity of an economy.

But that's the point. There are always going to be distortions. And only some of those distortions come from the government. Perfect markets don't exist and can't exist. They don't line up incentives as advertised, the incentive for the producer to take as much as possible from the consumer drives all kinds of insane and harmful unexpected behavior. And market competition doesn't keep that incentive in check as the theory holds, because all producers share the same incentive and their interests align. Government distortions are sometimes self serving as you've pointed out, but just as often they are attempts to counter act the distortions created by the markets themselves.

Economic theory has never been predictive to any reasonable margin of error. And a theory that cannot predict outcomes is not a valid theory.

> Perfect markets don't exist and can't exist.

Even diamonds are not perfect.

Perfection is good to have in models to demonstrate limiting cases, but not necessary to know the difference between situations where prices are allowed adjust and where prices are not allowed to adjust.

The "markets are not perfect" crowd loves to imagine the existence of a "perfect" and benevolent social planner who will always act according to their wishes. Let me know when you find one. (I know, "#realsocialism never been tried).

> Economic theory has never been predictive to any reasonable margin of error. And a theory that cannot predict outcomes is not a valid theory.

I find it ironic that you make this statement in the context of a clear cut demonstration of what happens when prices are not allowed to adjust.

There are a zillion markets across the world where one does not need to depend on the benevolence of the proprietor to get what you want or the benevolence of the customer to earn a living. Those get conveniently ignored.

If price controls worked so wonderfully, Uber, which was only an improvement on what was there before it and nothing close to "perfect", would not have become so popular. I would have loved for them to run a continuous double auction, but then nobody every gave me a billion dollars to burn.

> distortions created by the markets

By definition, distortions are created by interventions in markets.

> We produce 1.6x the amount of food the world needs. [...] By market theory, prices for food should be almost negative

Can I get a source for the 1.6x figure? I suspect it's 1.6x on the field, but doesn't factor in losses in transport/processing. By the same logic, we generate 110%[1] the amount of electricity that the world demands (at the power plant, 10% is lost due to transmission losses), therefore electricity prices should be negative as well.

So being able to get something after a wait is worse than not being able to access it at all by being priced out? That's a hot take.

Just because something is "priced" in a different quantity doesn't mean that it isn't cheaper or higher quality overall. That requires a more sophisticated argument than a simple observation that there's still some cost.

> the only effect of rationing a good is to change the currency in which that good is priced

This just sounds like an instance of the fact that a sufficiently abstract system of reasoning can be always be forced to described any particular patch of the world. Though typically at the cost of considerable contortions of the terms that makes no sense in other bits of the world.

For example, you may well say that "ability to navigate bureaucracy" is a currency. But it's hard to understand how you put that currency in a bank, in which sense this currency splits into perfectly equivalent units, or how it represents equivalent value at many different physical locations since the specific bureaucrats are tied a specific location.

By the way, picking an instance of cheating as some sort of general argument of why a specific system is not to be trusted is just a straw man, since the problem of cheating is independent on the exchange mechanism. Alternatively, accept this argument: scammers on Amazon prove that free market mechanisms don't reliably give a fair price.
