Here in the United States we have the Affordable Care Act (Obama Care) that guarantees insurance for those with previous medical conditions. Before that, private insurers' could, and most of the time would, reject insurer's who were unfortunate to have such a condition. Hard to put a price on that.

The ACA could be better with the originally included "Public Option", that includes a choice of either private or government coverage for those in need. This was rejected because most American Politicians do not want donors, such as Private Health Insurance Companies to loose out, and thus they, the politicians, would lose out on contributions (bribes).
Also as part of the ACA, individual States have a choice to accept money from the Federal Government for individuals who need help to pay for the Affordable Care Act. Most GOP States rejected that money simply because it had Obama's name attached to it. Bottom line, Obama Care can be greatly improved by at least allowing for the Public Option, either private or government covered insurance. Your choice. Nice to have choices. Either that or start over with a simple plan of Medicare for All.

Speaking of...

Sweden, Finland, Norway, Denmark, Italy, Ireland, New Zealand, Netherlands, UK, Germany, Austria, Canada, Australia, and every other civilized country are quite happy with government assisted "socialist" healthcare coverage. I doubt very much they would ever want to have to pay directly for, and deal with, private insurance companies, unless they want to. Again, nice to have choices.

Who's going to pay for Universal Health Care? The same citizens who currently pay for all other government run programs, you know, those socialist Roads and bridges they build, the socialist Police and Firemen that protect us, those socialist run Libraries, Medicare, Social Security, the VA, the U.S. Department of Agriculture, U.S. Department of Commerce, U.S. Department of Defense, U.S. Department of Education, U.S. Department of Energy. And yes the Socialist Military. (Speaking from experience, nothing is more socialist run than the U.S. Military.) The Department of Healthcare for All needs to be in that group and will actually reduce overall healthcare costs.

I'm done, I've said enough, This is a nice bar, but I talk too much, especially after having one too many.
