Yeah well, that's maybe an over active imagination.
The best healthcare systems in the world (with respect to quality, and quantity of people getting it) are public health systems.
So I dunno, I'd rather have the (functioning democratic) government, a body I actually have a stake in be in charge of health as opposed to a body that it's only duty is to it's share holders.
As I see it, a governmental body is (should be) something we all have equal share in independent of our financial situation. I'm quite aware to the ways this body could malfunction. But at least we have a moral footing to work against these malfunctions. With a public/private company as long as it makes money, I have no moral grounds to oppose it ruining my and our lives.
