The solution is to make the consumer participate in driving costs down. One employer I know of has an excellent solution to the problem: Make employees pay 100% of the bill up to a certain amount, such as $6000. That's a large amount, but the employer then contributes a large amount to your Health Savings Account (HSA), such as $4000. This amount is for you to keep regardless of whether you have any health bills or not. (This money can be used for medical expenses only, but can be used any time, including after retirement). So the maximum you will spend out of pocket per year is $2000. How does this encourage the consumer to scrutinize and control medical expenditure? Because the first $6000 of medical spending in a year is "your money". This is money you'd be able to keep in your HSA if you didn't have any medical expenses. This gives the consumer a strong incentive to reduce costs, question charges, avoid unnecessary services, and so on.
Also, I think emergency healthcare should be contemplated differently than ... I'll call it "premeditated healthcare". In one instance, the individual can make a deliberate shopping decision and weigh cost/benefit. That's fundamentally different than an ambulance taking you to the ER when you're bleeding out ... no price shopping then.
