Why Uncle Sam is Dr No of healthcare
"There is also no question of trying to exclude people with pre-existing illnesses from insurance, nor of charging some people and small businesses cripplingly high premiums because a family member or employee has had a disease. These activities keep US insurance companies busy and cost money. All other advanced countries shun them, designing their health systems to help people who need it, not to exclude them. In the US, insurance firms also compete to sell their health plans to employers and employees, running up marketing expenses that, of course, contribute nothing to preventing or curing any patient's illness.The insurance companies have created, among other things, a claims paperwork nightmare for patients, doctors, labs and hospitals that simply does not exist in a single-payer, universal health care system. In a typical doctor's office in the US there seem to be more clerks than nurses."
