Haha, no "socialist idiots"?
are you aware that, baring the Arab street, amusingly enough the majority of the worlds population is to the left of Obama?
Case in point: Germany
The CDU (which would be the left end of your repoblicans, they are in general in favor of state subsidies and limits to manager money) gets around 30%.
The FDP (which is the only party that is market liberal) is around 8-10.
The SPD (Socialist party, think of democrats slightly to the left of Obama) has roughly 20% overall (10% in east Germany)
The "Linke" (which means left, as a matter of fact they are so far to the left that they have no analogon in the US) gets around 10-20% overall, much more in the east, they are in several state gouverments, including Berlin.
The green party is solid at around 10%, they would be Al Gore in the US spectrum.
If a party with a US-like republican agenda (which would have to be Germanised) would in Germany, theyd get around 10-15 percent tops, maybe even less.
Basically, if "socialist idiots" would destroy nations, Europe would be much worse off, however it isnt, specifically concerning health care.
Secondly, Germany is likely the best example.
-A: The population is quite big, still around 82-85 million around 1/3-1/4 of the USA
-B: 15 millions of them are migrants. 2007 the number of migrants in the US was 37 million.
This means, per capita, Germany currently has more Migrants the the US.
Basically, Germany has more socialists (propably even in absolute numbers) and more migrants (relative to the total population) than the US, and doh, it works a fair bit better for us than yours does for you.
However, yes the administrative costs are quite significant, however, that is also the case for private insurances (as a matter of fact, the differences between the relative resources that German state and private insurance use for "administrative tasks" are suprisingly small), apart from that, state run insurances tend to be more lenient concerning paying for damages, however, due to the state concurence that is also true for private insurances, especially compared to US ones.
Last but not least:
Personally (mind you I am a student, so not that representative) I am using up around 8% of my funds for healthcare. How much do you pay?
Depends on what you consider worse off. We think the sky is falling if unemployment hits double digits, where that is typically normal over there.
I was thinking of worse off in terms of health, which was what the OP was about.
I defintly agree that Europeans consider beeing unemployed differently than Americans. In Europe (Germany at least) beeing unemployed will not directly threat your survival (due to still existing safety nets), what happens if European unemployed persons are, well, treated in the American way, is evident in France, they start kidnapping Managers and threatening to blow up factories. Vive la revolucion!
Considering prices are so expensive argument:
I had a subrenter from the US who basically said that Fuel and McDonalds are the only things that are more expensive in Europe than in the US.
Also, you cannot look at price differences in isolation, in Germany, money going to unemployed persons and money going to pensions still outdoes health care costs by a significant margin.
Considering "America rocks everyone else sucks".
I would make a point that a huge country with no direct competitors, vast amounts of land and resources and near easily exploitable markets would perform well under nearly any system of gouverment.
The system of gouverment is not the only thing that shapes the well beeing of a nation (especially you anti gouverment republicans should know that

), lets just compare the UDSSR and the USA.
Situation at the outbreak of the revolution:
USA: Wealthy
Russia: Straight out of a lost world war
How did the revolution go?
USA: relativly civilised affair
Russia: Large scale civil war
How did other powers react?
USA: Significant help from France, other important states beeing friendly, some minor interventions from unimportant german pseudostates.
Russia: Everyone apart from Germany (who were at war with Russia anyway) intervenes on behalf of the counterrevolutionaries, UDSSR stays an international phariah.
Who got into charge?
USA: People who were up to the task
UDSSR: The greatest crook of the communist party, who suceeded in first killing the competent part, than killing other crooks, than killing everyone else.
What happened later?
USA: A minor power thinks that blowing up some ships is a good idea
UDSSR: the strongest military of that times starts a suprise attacks and kills 20million.
To sum it up, the UDSSR was fighting the equivalent of the war of independence, the civil war (one with a particularly nasty streak) and World war one, and got Pearl Harbored on a much much much more massive scale at the moment it was going to recover a bit.
Oh, and 2 of the most murderous bastards of the country were in charge for the entire time, since the constant state of warfare didnt permit to set up checks and balances.
