Okay, let's bottom line it. Is health care a public service or a consumer good?
There's no debate, health care is a private good. National defense, border control, air traffic control, national parks, public highways, etc are public goods. Your consumption of national defense, that is, living in a society protected by an Army does no exclude me from enjoying the same benefit, same with you living in a city with a Fire Department or Police Department - you and I can both enjoy the benefits which derive from firemen conducting building inspections, from maintaining fire codes, from putting out fires and from police driving around and showing their presence, from enforcing traffic laws and thus scaring people into obeying speed limits, etc - the benefits we derive arise independent of our needing to have personal interactions with the fireman or the policeman.
When you get liposuction on your neck no one else but you benefits, just like when you eat an ice cream cone on a hot summer day only you get to enjoy the benefit of that particular ice cream cone.
Most of the rest of the world already had this conversation and decided it was a public service. As a result, they spend less and have better results.
This is simply an argument which mothers across time have battled when their children were caught succumbing to peer pressure - "If your friends jumped off a cliff, would you do so too?"
Look, we all understand that getting free stuff paid for by someone else is a very popular position, so it should be no surprise that lots of people favor such a position. I'd have no problem with sticking you with my annual gasoline costs to run my car, so why don't we socialize gas consumption - we all pay some annual ObamaGas fee and get to fill our cars with all the gas we want? How is that any different than socialized medicine?
As for spending less, that has nothing to do with socializing the costs (which actually put upward pressure on health expenditures because price discipline has been divorced from the consumer) and more to do with rationing. As for better results, that's hogwash, for what we see in the international comparisons is sloppy research design in that they don't control for racial variation. If the question is "What health outcome effects arise from socializing medical care" then researchers comparing Japanese healthcare to American healthcare are not telling us anything we want to know when they're comparing the health outcomes of Japanese citizens (combining both Japanese genetic and cultural patterns) against American citizens or multiple races.
Health care is already a collective. It's just a collective run by a private agency (insurance bought through employers) rather than a government.
Not really. There are plenty of people who CHOOSE to spend their money on other goods than health insurance. Some go completely without, others choose to self-finance regular physician visits and only insure against catastrophic events.
Most importantly, when one is unhappy with one health insurer then one can take up coverage from another and you can't do this when Uncle Sam is the only game in town.
Final point. The thing is, the current awful system you are already paying for. Because we spend 17% of our GDP on health care, spread out through the rest of the economy, it makes our goods and services less competitive than countries like Germany or Japan that have single payer and are only spending 8% of GDP and getting far better results.
We pay so much for healthcare because healthcare is what economists call a superior good, that is, the richer we become the more of it we consume, kind of like nice housing and luxury cars. Look at how much of your monthly budget is taken up by home-cooked food and compare to the percent of the monthly budget home-cooked food represents for a family in Ethiopia. Now compare food budget spent on eating out (a superior good) and you'll see that Americans eat-out at restaurant far more than do Ethiopians.
Germany is filled mostly with Germans, Japan with Japanese - they don't have vast black and Hispanic underclasses which have poorer health outcomes associated with race, not income.
