Maybe too much philosophizing for this, but here's my take.... the basic problem is that until the US decides that healthcare is a basic right/social good, it is a just going to remain a gigantic, difficult to regulate business with massive profits for the largest players.
People are now just so accustomed to looking at their health as a good with a risk/reward profile - especially on financial based websites. We buy insurance for ourselves as we do for our house and car. But fewer people (at least that I know personally) talk about the companies making a profit on their homeowners or car insurance (well, maybe on MMM) - however, they will say "my health insurer made x amount on me", with a negative connotation. Berkshire Hathaway makes a billion on GEICO car insurance - great! Aetna makes a billion on health insurance - they are screwing the public!
A US citizens health will just be a tradeable, marketable, expensive good until something changes. The insurance companies will continue to reap tremendous amounts of money based on the very real public fear that a catastrophic illness with bankrupt themselves and even their kids, etc, which is a very real threat. Just sad.
