I don't know if those against socialized medicine even understand economics. Like legitimately understand economics without their ideology getting in the way.
Healthcare in America is failing because:
1) Cost - Too high for most Americans to afford given the income spectrum
2) Quality - "Quality" is subjective, but you can measure it by looking at it's outcomes as provided by the many statistics of pages on this threads (life expectancy, infant mortality, etc...). Basically: for every dollar you put into the system, what kind of outcome do you get.
3) Coverage - Since insurance varies, some people have better insurance than others, and some have none at all
If you combine (1), (2), and (3).
This meets the definition of a market failure defined as: situation in which the allocation of goods and services is not efficient.
"Efficient" in this context is referring to
economic efficiency which consists of 2 parts:
(i) Allocation Efficiency - state of the economy in which production represents consumer preferences
(ii) Productive Efficiency - situation in which the economy could not produce any more of one good without sacrificing production of another good
(i) which essentially says, the economy shall produce what consumers want (i.e. market demand), and
(ii) which essentially says, goods and services are being produced at lowest possible cost hence... you cannot make 1 thing, but jack up the price of some other good
In the healthcare "market", the goods and services rendered are all the same. Human bodies work the same regardless of the health condition. The problem is allocation of resources in part (ii). Since a hospital or any medical facility has a finite amount of resources (beds/doctors/nurses/etc..), it has to make compromises between which goods and services to render first. Who do you think the hospital will prioritize in a free market? Obviously the patient who will pay the most money, not the most critical patients, hence the market failure.
This free market prioritizes the interests of money over health and is not efficient because it fails (i), since a less critical patient is being served before a more critical patient and (ii) the goods and services is not produced at the lowest possible cost since the price of some given good and service is priced according to what the market will demand... hence, the group of patients with the most money will raise prices for those with less money. But the group of patients with the most money is less than the group of patients with less money. Which equals poor outcomes for everybody. (51%+ of the population) The way the healthcare system operates now is largely based on this principle and the side effects (defined as "externalities" in economics), is what is bad. With externalities being, those poor health outcome statistics everyone likes to point out in support of socialized medicine.
To put this concept into real actual world example with economics. Let's assume you are a city of 99 people and a ballot measure reads the following:
Select whether you want to pay $20 or $100 to pay to fund the fire department.*
*If more than 50% of the people chooses $20, there will not be a fire department
^ The problem with this as most conservatives will point out is the free-rider issue. Some people will benefit without paying. If less than 50% of the people chooses to pay $100, there will be a fire department that serves the entire community, but at least 51% of the people benefit from the service without paying. But in the free market, do you want to pay $20 or $100? If you choose $20 (which most will), nobody will have a fire department, which benefits
no one. So... to sum it up: your individual self-interest ends up hurting everyone as a whole since the city now has no fire department. So how do you fix this problem? In come Uncle Sam with something everyone loves to pay called,
taxation.
