And the counterpoints...
1) Right now America's biggest problem isn't doctors testing too much - it's too LITTLE testing. Americans don't do any preventative medicine choosing to go to the doctor only when the damage done is already severe.
Guess what - early detection and preventative care is not only better for saving lives, it generally costs a lot less to provide.
The old adage goes that "early detection of cancer means before there are serious symptoms" - how do you equate that with a system where people are afraid to go to a doctor until the symptoms are severe ?
More importantly - I didn't say medicine should always be provided by the government, there are some possible valid concerns there though it's clear to me that your "medicine market" system comes down to saying "the right to life is on the lawbooks but only for rich people". I put "socialized medicine" in quotes on purpose - specifically to point out that I am using the term as it's use by America concervatives - to mean "any medicine not supplied with the intention of maximizing corporate profits.
The point is - I think the vast majority of Americans would get better and more frequent medical care even with the kind of government run single-payer form of universal healthcare found in countries like cuba.
My own country uses multipayer universal healthcare e.g. there are both private medical facilities and public ones. Medical insurance companies (who generally take bulk contracts with employers offering you better rates) that pay for private care, while public is free-for-all.
The catch here is that we're a very poor country - so public means long waits and overworked staff. Despite that, a few years ago I got in a motorcycle crash when I was uninsured, went to a public hospital and got excellent care and thus survived without any lasting injuries.
Brazil is just a little richer than my native South Africa, I used to be a very regular traveler there. They too have multipayer system like we do, but they have a somewhat richer country. On one of my trips I got sick, simple virus infection. Here - I would save my precious medical-savings-account (insurance part only kicks in if you're hospitalized) and just heal up at home.
There I was instantly dragged to a clinic by my hosts. True I had to wait about two hours to be helped (if I went to a private one with an appointment I could skip that, but I'd literally be paying for the convenience - the care is identical).
Once I got to a doctor though, I was fully examined. I was then prescribed a course of immune-boosting vitamins, given 3 hours of pure oxygen (another immune booster) and a series of shots to prevent secondary infections... basically 5 hours of care (suddenly waiting 2 hours isn't so bad by comparison).
Whereas normally a flu virus knocks me out for up to two weeks, I was back on my feet in 3 days.
For 86 out of 100 patients - this care won't save their lives, just get them back to work a bit quicker (hmmm isn't that GOOD for the economy ?) but now what about that 14% of people in whom influenza is fatal ? This kind of treatment probably drops the fatality rate in that country to 7% or lower (I haven't checked the numbers - but it's obvious that massive preventative care in patients having a disease with a low fatality rate would lower it).
And do you know what I paid for all those shots, the oxygen treatment, the doctor's time and the huge bottle of pills they gave me ? Squat. No bill. Not even one penny. It's free - even to a foreign tourist. The form I was given to fill in had a place for my name and age, the rest of it was valid questions on my medical history. Nobody cared about my billing address.
If Brazil can afford to give high quality medical care to it's citizens for free - America has no excuse.
Do you realize that America is the ONLY industrialized nation on the PLANET with no guaranteed free healthcare option available to all citizens ? There isn't even ONE other industrialized country where poor people HAVE to die from curable diseases because they can't afford the medicine.
I can understand that happening in Sudan where doctors are rare and money even rarer... no amount of rhetoric can excuse it happening in New York City.
I have traveled extensively in my life (18 countries and counting - most of them poor nations) the only one where I really FEARED getting sick... was yours.
