Don't want to get too political but you do realize that the USA has the most expensive healthcare and the least amount of government involvement? And the worst outcomes.
We don't have the least amount of government involvement. We're #3 in the world in terms of government spending, at least. (Measuring regulatory involvement, which includes things like lawsuit-preventative medicine, is trickier.)
It's a combination of all those factors, plus other factors like lawsuits and such, that, in my opinion, combine to make medical care so expensive here.
I'm not sure how your question relates to my comment.

If you want to see little government involvement, look at India (that's where I go when I need work done).
