I don't advocate government regulation; but if they are going to do anything about healthcare, it should start at regulating the COST of healthcare. Lack of insurance is not the problem; it's the symptom. Another issue creating higher healthcare costs that should be looked at are fraudulent malpractice suits, not enough doctors, and non-payment for services.
Fix those first, and then it won't really matter if people have or no insurance. Why? Well for starters the cost of healthcare would be lower and more affordable, and making healthcare affordable will automatically make insurance affordable. People will be able to get off HMO plans and go back to a major medical insurance model.
