Myth # 1 - We drink and smoke to much. We do but Europeans do both a lot more than we do.
Myth # 2 - America has a larger elderly population. We don't.
Myth # 3 - Obesity in America skyrockets costs. It is a problem but the total cost is estimated at about $25 billion, a small fraction of overall costs.
Myth # 4 - Malpractice costs are out of control. Malpractice adds 2% to the cost of healthcare. Still too high but most malpractice suits are not frivolous as some claim.
Truth # 1 - Providers charge more because they can. On average, medication costs 118% what it does in other countries. The Bush Medicare Prescription Act for example forbade the government from negotiating for lower prices.
Truth # 2 - Administrative overhead is out of control. 21% of our excess spending on health care is administrative and is double the cost per capital of the next highest country.
Truth # 3 - Massive outpatient costs. Hospitals provide incentives for quicker procedures to get higher profits.
Truth # 4 - Doctors are overpaid. In America doctors make 5 times more than their patients. In other developed countries they make 3 times more than their patients.
