I'm the downvotee. I think they understand economics. Who doesn't? What they refuse to admit is:

1) Healthcare is a limited resource, like anything else.

2) Prevention, which few if any "leaders" highlight, is a viable alternative to healthcare price increases.

Are there there some nefarious undercurrents? Yes, of course. But to blame all our ills - and remove diet, lifestyle, etc. - on ever increasing demand only makes the current system stronger. People who believe they have no control aren't part of the solution.
