I think that the more certainty people have about their future medical issues the less likely health care plan groups are to work. What incentive does a future-healthy person have to join with someone who is certain to have high expenses? And why would you trust someone to tell you that they haven't been tested and know what lies ahead?
That's what I'm getting at. The more knowledge all the participants have (and that's both insurance and users), the more the fundamental contradictions between "insurance" and "health care plans" emerge. But closing your eyes and just remaining ignorant is a terrible choice too, because in the medical domain, knowledge isn't just power, it's life.
