>>> The Oregon trial had no effect on diabetes. It caused people to consume more diabetes medication which the authors speculate might make them healthier.
It increased the rate of diagnosis of diabetes. And what do you mean speculate? What's the point of giving medication if it doesn't help?
>>> You are correct that having insurance made people feel better. So what?
Treating depression is part of healthcare.
>>> And you've just demonstrated that you have goals here other than finding truth
I don't think so. I just thought it's an interesting observation. Combined with the fact that it was a short term experiment it makes one think. But you're right, it's not significant.
>>> "stop smoking" and "stop drinking" support, not medical interventions
Stopping smoking and drinking is part of healthcare. At least in the UK. Perhaps you don't think preventive care works because you don't think improving ones wellness is part of it? Why are insurance companies including preventative care in their packages if it actually costs them money?
Here's a study that found a list of preventative measures that do save money: vaccinating children and adults, smoking cessation, daily use of aspirin, and screening for issues with alcoholism, obesity, and vision failure.

But you're right. In part. Other preventative measures do not save money. Like preventing heart attacks by treating hypertension early on with drugs did not save money in the long run. It's more cost effective to let people have heart attacks. But at least the insurance company saves a few bucks (rolls eyes).
