The insurance industry has perverted our healthcare system. The major reason doctors moved from private practice to being associated with hospitals is to simplify billing because health insurance companies look for any reason to refuse payment. To reverse this trend, we need more people willing to bypass insurance and buy healthcare directly.
Health insurance is a failed experiment. People should pay for their healthcare directly, and the government should provide for those who require serious, expensive treatments (after a payment that is some percentage of their income).
