I write this with complete awareness of the stars in my eyes, but I've always liked the way they used to do it in China. Each village had a doctor, and all villagers paid the doctor as long as they stayed well. When they got sick, they stopped paying, till they got well again. Since TCM (Traditional Chinese Medicine) includes diet and exercise as well as herbs and acupuncture, each villager shared responsibility for staying healthy with the doc.
Because docs got paid for keeping folks well, rather than getting paid for treating them for illness, they learned to detect and remediate imbalances in the system long before any serious disease manifested.
I guess the main idea here is, we have a health care system that is all about sickness, crisis management if you will, rather than about wellness and crisis prevention. Seems pretty wack to me.
