Is there an industry where the consumer determines the cost of the service/product when they purchase it? Seems to me that the market determines the price. I know I set my own rates. More than once a potential customer has said "Ohhh, that's too much. Can you do it for less?" At that point, I decide to cut my rate or not. If not, the customer then decides to accept my rate or seek a better one. It's kind of how our economy works. Why should the medical field be different?
Of course, an alternative is to make all medical personnel government employees. The government sets their paygrade and provides medical attention to anyone who seeks it. No health insurance just proof of citizenship. I'd much prefer that over Obamacare.
