I like Trump's approach that instead of focusing on health insurance, hospitals should publish their rates publicly for people to decide which one to chose over which.
That hospitals hide their rate and come up with astonishing bills afterwards is a root problem. And we should be able to get a picture of the bill even before getting a quote from them.
In case of uncertain bills, the median amount should be published.
Full transparency on what you get for what amount of price is key to business, commerce and success.
