If it’s price signals and competition you’re after, why not cut out the middleman and have consumers pay doctors directly? For example, imagine a national healthcare plan that paid 75% of all medical expenses but required you to pay the other 25%. Your maximum out-of-pocket expense each year would be capped at, say, 5% of income at low income levels, 15% in the middle, 30% at the next level, and 50% for the rich.
