Medical care like utility services is definitely not a free market economy as is said by almost every economist. 

Government does need to intervene and regulate the industry for the benefit of the people and not the greedy.

No one can say we look for the cheapest medical care. We look for the most expensive and best. And utilities which succeed in an unregulated economy tend to charge whatever the market can afford when they become a monopoly. Government needs to step in to regulate profits and ensure service and safe operation. 

And for medical care, since cost can become expectedly huge, insurance is needed through third parties. This just increases the administrative costs for a health program greatly. It's the reason we have so expensive Healthcare in the US and we are just on par with foreign countries who charge much less. Let's let the doctors keep the profits and not the lawyers.
