Anger is insufficient. Without consumer choice, there is no mechanism for individuals to impose pressure on Healthcare providers and insurers. They can continue to 'milk the cow'.
Just give consumers access to a price list before service is provided. That will go a long way towards helping the problem. (Not that you are going to price shop for every service--a trip to the emergency room for a broken bone wonte get shopped--but some portion of health Care is discretionary or is deliberate enough it can be shopped.)
That’d lower the cost of the average policy as their would be an influx of (on average) healthier people to the market for insurance.
