Who said anything about the government doing it?  

I didn't say that, you start with programs like Massachusetts and Hawaii have where a combination of individual mandates, employer contribution, and health insurance responsibility are required. That gets you these kinds of results, look at who has the most access to health care and who has the most people covered...

Now you've got the majority of people covered, the remaining less than 5% becomes a manageable proposition. That's where you need a new and improved ACA to cover those remaining people, it has to take advantage of every tool available to provide quality care plans that are affordable, buying across state lines, etc. 

That will leave you with 1-2 percent of folks who are destitute, very old etc. These people will have to be subsidized by federal and state programs, but if you do everything else you're talking about a relatively small number of people and a manageable cost. These people are being subsidized already but in the wrong way, they use hospital emergency rooms as doctor's offices at a ridiculous cost. They should have a subsidized health care plan and go to an HMO like everyone else. 

I'm not talking about a government take over of the American health care system, I'm talking keeping our current system and improving it. And getting the entire population on high quality affordable health care plans. 

It can be done, as I mentioned several states have already taken this approach and have outstanding results to show for it.
