About the article "Germany", section "Health".

Candidate passages:
It begins by examining how three fundamental facts about health care systems.
The potential exists to spend the entire US GDP on health care in useful ways.
As time goes on, Americans desire to spend more of their income on health care.
The US has suppressed normal market forces in dealing with 1 and 2.
The authors contend that Americans could potentially spend their entire GDP on medical testing alone.
They further explain that as people become older and wealthier, they naturally spend more of their money on health care.
They explain how the suppression of normal market forces, in conjunction with the first two facts, has created the problems currently faced with health care in the United States and abroad. 
Relative to the rest of Latin America, Peru does not spend very much on health care for its citizens.
2004 reports showed that spending in Peru was 3.5 percent of its GDP, compared to 7 percent for the rest of Latin America.
Additionally, Peru spent $100 USD per capita on health in 2004, compared to an average of $262 USD per capita that was spent by the rest of the countries in Latin America.
However, Peru does spend more on healthcare than it does on its military, which differentiates it from many other Latin American countries. 
Public positions.
Health care.
Buffett has described the health care reform under President Barack Obama as insufficient to deal with the costs of health care in the US, though he supports its aim of expanding health insurance coverage.
Buffett compared health care costs to a tapeworm, saying that they compromise US economic competitiveness by increasing manufacturing costs.
Buffett thinks health care costs should head towards 13 to 14% of GDP.
(Under the Patient Protection and Affordable Care Act, the CMS actuary has projected health care costs will reach almost 20% of GDP by 2020.)
Buffett said "if you want the very best, I mean if you want to spend a million dollars to prolong your life 3 months in a coma or something" then the US is probably the best, but that other countries spend much less and receive much more in health care value (visits, hospital beds, doctors and nurses per capita).
Buffett faults the incentives in the US medical industry, that payers reimburse doctors for procedures (fee-for-service) leading to unnecessary care (overutilization), instead of paying for results.
Buffett has cited Atul Gawande's 2009 article in the "New Yorker" as being a useful study in the problems of US health care, with its documentation of unwarranted variation in Medicare expenditures between McAllen, Texas and El Paso, Texas.
Buffett also brought up the problem of lobbying by the medical industry, saying that they are very focused on maintaining their income. 
In 1997, Argentina spent 8% of its GDP on health care expenditures.
A 2011 comparative report found that the average doctor's visit in Argentina cost about USD$9. 
In Israel, the publicly funded medical system is universal and compulsory.
In 2005, Israel spent 7.8% of GDP on health care, or US$1,533 per capita.
Of that, approximately 66% was government expenditure.
