Yes, there is something wrong with the insurance industry. But there is something wrong with the hospitals, doctors and drug companies too. The whole system is broken. Hospitals try to eke out the most out of insurance companies, often providing services that are unnecessary. Pharmaceutical companies charge US patients significantly higher rates than in other countries. Don't put all the blame on insurance companies.
If Americans had the fortitude to have grown-up conversations about what should be socialized, how care should be rationed, etc, the public could exert some control over the design of the "system". As it stands, the "system" has mostly been shaped by corporate interests while the public has been distracted by inflammatory rhetoric pumped-out by all the entrenched players designed to play to partisan feelings about "fairness" and "freedom".
